A detailed performance evaluation was carried out considering detection accuracy, usability and availability. The available technologies are divided into four categories: wearables, surfaces with embedded sensors, vision- and environmental-based solutions, and smart containers. This paper reviews the most recent solutions to automatic fluid intake monitoring both commercially and in the literature. Real-time systems for monitoring fluid intake will not only measure the exact amount consumed by the users, but could also motivate people to maintain a healthy lifestyle by providing feedback to encourage them to hydrate regularly throughout the day. Numerous critical health problems are associated with poor or excessive drinking such as swelling of the brain and heart failure. This work demonstrates the feasibility of real-time bioimpedance measurements for at home health and fitness monitoring and discusses possible improvements of the measurements and assessment of the hydration results.įluid intake monitoring is an essential component in preventing dehydration and overhydration, especially for the senior population. Measurements at 8, 16, 32, and 50 KHz are presented and some of the challenges and possible solutions for real-time system implementation are discussed.
#Smart reminder water bottle Bluetooth#
The prototype was developed in the form of a smart water bottle, a Texas Instruments AFE4300 integrated analog front end, a Teensy LC microcontroller, a Bluetooth module, and a Windows application for the control program.
#Smart reminder water bottle software#
This thesis demonstrates an implementation of a low-power embedded software for bioimpedance measurements that can be used for hydration monitoring. This method can be applied to Internet of Things (IoT), fitness, and clinical devices to facilitate health monitoring and provide warnings in the case of dehydration.
By injecting small currents at different frequency and measurement of complex impedance, we can assess the amount of ICW, ECW, and TBW. Complex impedance of the body is a function of frequency and amount of ICW and ECW. It can be particularly used for evaluating the hydration level of an individual based on the amount of intracellular water (ICW) and extracellular water (ECW) in total body water (TBW). Bioimpedance analysis (BIA) is a convenient and highly accurate method for assessment of the internal composition of the body.
