Disposable sensor patch analyses golfers’ swing
In one commercial application to be demonstrated at the Printed Electronics Europe trade show on April 28-29, 2015 in Berlin, the patch is being used to power a new sensor that allows golfers to accurately track the swing of a club.
Only a few millimetres thick, the 70x23mm patch is attached to a golf club head for measuring acceleration and angular velocity and the acquired data is directly transferred after each stroke via low energy Bluetooth (BLE) to an application on a mobile device. This way the disposable patch is helping golf players improve their swing, with instant feedback from the club head.
“For these one-time use patches, we’ve been working on the assumption that the patch would be used for a two-hours training session with over a hundred strokes, but the platform could be delivered with other sensors and have different data acquisition requirements depending on the sport”, told us Anja Talo, Enfucell’s Sales Director.
The Swedish company has integrated all the sensors and the Bluetooth radio together with its thin printed power source to offer a sleek prototyping platform that could power the BLE data transmission without additional capacitor. It is now talking to potential customers who could be interested in licensing the platform to develop their own sensor patches.
Designed as a demonstrator, such a lightweight, easy to stick sensor solution offers plenty of coaching opportunities in sports but it could probably find its way in many other monitoring applications, including where multiple wireless sensors would be required. A similar patch could be tailored for other racquet sports, shooting, bowling, etc.
