Abstract
The aim of this thesis was to develop a way to evaluate the mobility of the wrist or hand after an injury.
To do this a prototype of a compression glove with added conductive silicone was made. A tensile test was done first to test linearity between resistance and elongation. Thereafter this was implemented on the prototype. The silicone, Elastosil LR3162 showed good proprieties for the purpose when stretching the fabric. The results showed linear behavior and also a large indication when changing the resistance .
Wearing the prototype glove and bending the hand will stretch the silicone. When bending it is thus possible to measure the change in resistance. The readings can thereafter be converted to angular displacement from a given... (More)

The final goal is to further develop this idea and send the readings with a bluetooth device to an application in the patients mobile phone.
This project is delimited to evaluate Elastosil as a suitable material, to develop a simple prototype, and to suggest how to proceed. (Less)

Smart sensor for wrist movements
What if you could follow your own recovery after an injury? This project is about finding a way to evaluate the mobility of the hand and wrist using a conductive silicone painted on a glove.
