-While reusable bottles are generally more sustainable and economical, they also require regular cleaning. Observations of user behavior suggest that many consumers frequently refill their bottles without cleaning them sufficiently. A major theoretical challenge is the hygiene gap, because these bottles often harbor heterotrophic plate counts (HPC), which include bacteria, yeast, and mold [(Sun2017]. In the EU, the safety limit of 100 CFU/mL is frequently exceeded because users often refill bottles without sufficient cleaning [(Bartram2002)]. Microorganisms form biofilms on internal surfaces, especially when nutrients are present and disinfectants are absent, potentially leading to foodborne illnesses in vulnerable groups [(WHO2022]. +While reusable bottles are generally more sustainable and economical, they also require regular cleaning.

-The **LARQ Bottle PureVis** focuses primarily on water hygiene rather than hydration tracking. Its key feature is an integrated UV-C LED system, which disinfects both the water and the inner surface of the bottle. The UV-C light can be activated manually or automatically at regular intervals to eliminate up to 99.99 % of bacteria and viruses inside the bottle. The desinfection process takes 10 seconds. Some versions also include optional hydration tracking via a smartphone app and may be equipped with a replaceable filter to remove contaminants such as chlorine or heavy metals. The bottle is typically available in 500 ml and 740 ml versions, weighing around 380 g and 500 g. Thanks to its double-walled stainless-steel insulation, it can keep drinks cold for up to 24 hours and hot for about 12 hours. With a price range of about 90 € to 120 €, the LARQ bottle is relatively expensive, but its main advantage lies in the self-cleaning function and improved water hygiene, making it particularly suitable for travel and outdoor use [( LARQ Bottle PureVis™, https://www.livelarq.com/de/purification/larq-bottle-purevis-insulated-monaco-blue?size=500ml [Accessed in March 2026].)]. +The **LARQ Bottle PureVis** focuses primarily on water hygiene rather than hydration tracking.

-In contrast, the **HidrateSpark Pro Tumbler** focuses on hydration monitoring and behavioral motivation. The bottle contains a sensor in the base that measures the water level, allowing it to automatically track how much water the user drinks. The data is transmitted via Bluetooth to a smartphone app, where users can monitor their hydration level, set personal drinking goals, and view statistics or achievements. A distinctive feature of this bottle is its LED light system, which lights up in different colors to remind users to drink throughout the day. The bottle can also integrate with health platforms such as Apple Health and it supports Apple Find My for locating the bottle. The bottle typically has a capacity of about 620 ml, weighs around 400 g to 500 g, and costs approximately 70 € to 90 €. Its main advantage is the automatic tracking of drinking behavior, although it requires charging and may occasionally experience Bluetooth connectivity issues [(HidrateSpark PRO Tumbler, https://hidratespark.com/?srsltid=AfmBOoqcd17md6qA4ce2pqSTmnwlLQ3F9yxDL9KTQMlmENRpAe02tGlv [Accessed in March 2026].)].+In contrast, the **HidrateSpark Pro Tumbler** focuses on hydration monitoring and behavioral motivation.

-The **Ozmo Active** Smart Bottle extends the concept of hydration tracking by integrating fitness and lifestyle data. Similar to the HidrateSpark bottle, it uses sensors to measure fluid intake and sends the data to a smartphone app via Bluetooth. However, a key difference is that the Ozmo system can distinguish between different beverages, such as water and coffee, allowing users to monitor their total fluid consumption more comprehensively. The system also provides hydration reminders and integrates fitness and health platforms, linking hydration with physical activity data. The bottle has a capacity of around 600 ml, weighs approximately 400 g to 450 g, and costs around 60 € to 80 €. While the ability to track multiple beverage types provides a broader overview of fluid intake, the system can be more complex to use and mainly targets users interested in detailed health and fitness monitoring [(Smart Water Bottles, https://medium.com/@MAMeer841/smart-water-bottles-542b6ffbbe87 [Accessed in March 2026].)].+The **Ozmo Active** Smart Bottle extends the concept of hydration tracking by integrating fitness and lifestyle data.

-The **equa** Smart Water Bottle, on the other hand, focuses on simplicity and user motivation. Its main feature is a light signal integrated into the bottle, which illuminates to remind the user to drink regularly. The bottle connects via Bluetooth to the EQUA Hydration App, where the user’s daily water intake is tracked. The app also calculates a recommended daily hydration level based on personal parameters, such as body characteristics and activity level. In contrast to more sensor-focused systems, the Equa bottle mainly encourages hydration through reminders and app-based tracking rather than precise intake measurement. The bottle is made of double-walled, vacuum-insulated stainless steel, has a capacity of 680 ml, and weighs around 350 g to 400 g. Its typical price is 70 € to 90 €. The main advantage of the Equa bottle is its simple and intuitive reminder system, although, like other smart bottles, it requires charging and is more expensive than conventional bottles [(Smart Thermo Bottles https://myequa.com/collections/smart-bottle-with-glow-reminders/products/smart-snow-white-water-bottle [Accessed in March 2026].)].+The **equa** Smart Water Bottle, on the other hand, focuses on simplicity and user motivation.

 Overall, these products demonstrate different approaches to smart hydration systems. While the LARQ bottle emphasizes water purification, the HidrateSpark focuses on precise hydration tracking, the Ozmo system integrates hydration with broader health data, and the Equa bottle prioritizes simple reminders and user motivation. These differences highlight the range of possible functionalities and design strategies that can be considered when developing a new smart water bottle system. It turns out that all these areas, disinfection, water quality control, quantity tracking, and motivation and overview via a connected app, are already covered by individual bottles. However, there is currently no water bottle that combines all these aspects. Overall, these products demonstrate different approaches to smart hydration systems.

-Various projects have used clinical settings to test the efficacy of smart hardware. A randomized trial showed that patients using smart bottles with integrated hydration reminders achieved a much higher daily fluid intake compared to a control group [(Thomas E. Stout et al., 2022. A Randomized Trial Evaluating the Use of a Smart Water Bottle to Increase Fluid Intake in Stone Formers, https://pubmed.ncbi.nlm.nih.gov/35283036/ [Accessed in March 2026].)]. Similarly, research involving college students demonstrated that digital feedback loops and historical data provided via an app significantly increase a user's awareness of their hydration patterns [(YuChun Chen et al., 2023.

-The study [(Xiaodi Sun et al., 2017. The Cleanliness of Reusable Water Bottles: How Contamination Levels are Affected by Bottle Usage and Cleaning Behaviors of Bottle Owners, https://www.foodprotection.org/members/fpt-archive-articles/2017-11-the-cleanliness-of-reusable-water-bottles-how-contamination-levels-are-affected-by-bottle-us/ [Accessed in March 2026].)] found that more than 20 % of reusable bottles had bacterial counts that exceeded the limit. Organic substances are referred to as heterotrophic plate count (HPC) and include mold, bacteria, and yeast.  Different countries have different limit values for HPC in tap water [( J. Bartram et al., 2002. Heterotrophic plate count measurement in drinking watersafety management Report of an Expert Meeting Geneva, 24–25 April 2002. https://cdi.mecon.gob.ar/bases/docelec/dp1368.pdf, [Accessed in March 2026].)]. In the EU, the limit is 100 CFU/ml which is exceeded in many water bottles even though the tap water used to fill them is clean. The Colony Forming Units per milliliter (CFU/ml) is a measure for the number of living, reproducible bacteria or fungi in a liquid sample [(Xiaodi Sun et al., 2017.

Improperly cleaned bottles may therefore present a contamination risk and potentially contribute to foodborne illness, especially for vulnerable groups such as children, older adults, or immunocompromised individuals. Microorganisms commonly grow in water and on surfaces in contact with water in the form of biofilms, particularly when nutrients are available and no disinfectant is present [(World Health Organization, 2022. Guidelines for drinking‑water quality, Fourth edition incorporating the first and second addenda, https://www.who.int/publications/i/item/9789241549950 [Accessed in March 2026].)].  +The study [(Sun2017)] found that more than 20 % of reusable bottles had bacterial counts that exceeded the limit.

-A major project-based advancement in smart bottles is the implementation of UV-C LED technology for internal sterilization. This addresses the hygiene problem of bacteria, yeast and mold without requiring physical filters or chemicals. It turns a standard container into a self-cleaning medical-grade device. There is a new approach in which the UV-C light spectrum is used to disinfect both the water and the bottle itself.  The spectrum range between 250 nm and 280 nm is crucial. Only this can ensure that the DNA and mRNA of the microorganisms in the water are destroyed and the organic matter is killed. It is also important that the inner surface of the bottle is reflective and that all materials exposed to the light are UV-C resistant [(Neeil Gandhi et al., 2021. Documentation Smart Water Bottle Senior Design 1 https://www.ece.ucf.edu/seniordesign/su2021fa2021/g05/FLASC/Documentation/SD1initialprojectdescription2.pdf [Accessed in March 2026].)]. This concept will be introduced in connection with the products of the company LARQ and ensures that organic contaminants are eliminated.  +A major project-based advancement in smart bottles is the implementation of UV-C LED technology for internal sterilization.

-The development of smart reusable bottles is also a response to the global plastic crisis. Normal plastic water bottles have a significant environmental impact throughout their entire life cycle. Studies have shown that bottled water can have an environmental footprint up to 3 500 times greater than tap water, mainly due to plastic production, packaging, transportation, and waste management. The manufacturing of single-use plastic bottles requires large amounts of energy and fossil resources, which contributes to greenhouse gas emissions [(Joey Grostern, 2021. The Guardian: Environmental impact of bottled water ‘up to 3,500 times greater than tap water’ 5th August 2021. https://www.theguardian.com/environment/2021/aug/05/environmental-impact-of-bottled-water-up-to-3500-times-greater-than-tap-water [Accessed in March 2026].)]. In addition, many plastic bottles are not properly recycled and end up in landfills or in natural environments such as rivers and oceans. This can lead to long-term pollution, the formation of microplastics, and harm to wildlife that may ingest or become trapped in plastic waste. These consequences highlight the environmental importance of reducing single-use plastic bottles and promoting reusable and more sustainable alternatives. The use of reusable bottles is one opportunity to reduce the consumption of plastic bottles and therefore offer a way to face the environmental impact [(Pascal Nuti, 2023. Lavie: Welche Umweltauswirkungen haben Wasserflaschen aus Plastik und wie kann man sie vermeiden? https://lavie.bio/de/blog/umweltauswirkungen-wasserflaschen-plastik/ [Accessed in March 2026].)].+The development of smart reusable bottles is also a response to the global plastic crisis.

-Recent research projects are exploring the integration of advanced sensors into portable bottles to detect specific contaminants and monitor real-time mineral content. While no commercial bottle currently measures TDS or minerals directly, studies have proven the health benefits of such data [(Ananta Jadhav et al.,2025. Impact of drinking water TDS on serum calcium and magnesium levels: A Cross-Sectional Study, https://ijmscrr.in/index.php/ijmscrr/article/view/1292 [Accessed in March 2026].)]. Current project goals focus on overcoming technical hurdles like sensor miniaturization and power consumption to make these features a reality in everyday life. +Recent research projects are exploring the integration of advanced sensors into portable bottles to detect specific contaminants and monitor real-time mineral content.

-The analysis of existing concepts, projects and smart water bottles shows that many products address individual aspects of hydration and water quality. Some focus on hydration tracking and behavioral motivation through smartphone apps, while others integrate UV-C technology for disinfection or include filtration systems. However, there is currently no product on the market that combines UV-C disinfection, water filtration, volume tracking, mineral content measurement, and a user-friendly app with gamification in one integrated system. While individual features exist across different products, they have not yet been combined into a single solution. This represents a potential market opportunity for the TRAQUA concept.  +The analysis of existing concepts, projects and smart water bottles shows that many products address individual aspects of hydration and water quality.

However, there is currently no product on the market that combines UV-C disinfection, water filtration, volume tracking, mineral content measurement, and a user-friendly app with gamification in one integrated system. While individual features exist across different products, they have not yet been combined into a single solution. This represents a potential market opportunity for the TRAQUA concept.

 At the same time, there is a growing trend toward tracking everyday behavior and focusing more on personal health and wellbeing. People increasingly monitor activity, sleep, and nutrition using digital tools. However, hydration and especially bottle hygiene are often neglected. Studies show that reusable water bottles are frequently not cleaned adequately, which can lead to bacterial growth, and many people drink less water than recommended. Research also demonstrates that digital reminders and tracking apps can significantly increase daily water intake.  At the same time, there is a growing trend toward tracking everyday behavior and focusing more on personal health and wellbeing.
