4M.
This was my major project completed as part of my Integrated Industrial Design MSc at Loughborough University. The project focused on prevention and rehabilitation of sporting injuries, which lead to a wearable device designed to monitor users form throughout exercise.
The silicone devices contain 3-Axis accelerometers which are used as dynamic inclination monitors. By constantly tracking the angles of the users limbs, the device can identify errors in the users movements. 

The final design is a wearable accelerometer which connects to a user’s phone through Bluetooth. The product would be sold in pairs and can be used in a modular fashion to suit the user’s needs. Using more sensors would add more detail to the measurements being taken. 
Wearable straps enable the monitoring of the users form through a wide range of lower limb exercises. By connecting the sensors to an application, the angles of a user’s leg are calculated to accurately assess their form. This can be viewed by the user through a graph showing the changes in angles of their exercises, or through a graphic which uses measurements to create an avatar which performs the exercises on screen. This can then be compared to a pre-set in which the “ideal form” is displayed. With relevant programming, this screen-based user interface would be accessible through a user’s mobile phone or computer. For those recovering from injury, their physiotherapists could also access the data. This capability would enable the user to identify weaknesses in their movements and target specific areas in which they need to improve.
