Real-time hydration advice from new ‘smart’ drinks bottle

In physically demanding scenarios, levels of hydration can have a significant impact on performance, and the i-dration hardware app encourages athletes to drink when they need to, rather than only when they feel thirsty. Drinking too much water can have an equally negative effect on sports performance as drinking too little, so Cambridge Consultants designed the i-dration to ensure that users maintain a proper balance of hydration for optimum performance.

The device works by giving advice based on real-time data gathered by the bottle, which is transmitted wirelessly to a smartphone application. Intelligent sensors in the i-dration bottle can be used to monitor the external temperature, drinking frequency and quantity, and this data is then sent via Bluetooth to its user’s smartphone. The phone’s inbuilt accelerometer and gyroscope can measure exercise levels, and by ‘fusing’ the data from a heart rate chest-band and information pre-entered using the smartphone interface (such as height, age and weight), the application can perform an assessment of a user’s hydration levels. The i-dration bottle then responds accordingly by flashing a blue light if the athlete needs to drink more.

i-dration demonstrates the work that Cambridge Consultants is currently undertaking in bringing mobile applications to life. “Most people still perceive an ‘app’ to be something that performs a certain task, whether it’s checking the weather or the latest sports results, in a virtual world. However, we believe that in the next 12 to 18 months we will see a plethora of  new dedicated ‘hardware apps’, such as the i-dration drinks bottle, that will work in tandem with a smartphone to enhance a range of consumer products and services ,” said Rachel Harker, Business Development Manager at Cambridge Consultants. “Whilst smartphones have some excellent capabilities, it is not always practical to use the device itself for collecting or displaying data. Inexpensive, wireless hardware apps have the potential to increase the versatility of smartphones. In the case of the i-dration bottle, it’s also relevant to the increasing number of consumers who view their smartphones and technology products as integral to maintaining their health and wellness.”

Such ‘sensor fusion’ algorithms, where the data from multiple sensors are fused together, are typically found in large distributed software systems, but can now be applied to smartphones with Internet connections working with dedicated hardware apps. Cambridge Consultants has the technology and the expertise to develop hardware apps for a vast range of functions, including the signal processing required for real time processing of the algorithms, at a low enough cost-point to make them commercially viable. Using this innovative approach, ‘hardware apps’ can be developed for multiple markets, including the medical and security sectors.
