| Abstract: | Limitation of hand function can have a significant impact on quality of life. The e-Cone is a prototype grip strength measurement system for patient rehabilitation. In a previous research, a 64x64 pressure sensor was developed. It consists of two flexible PCBs with a layer of pressure sensitive Velostat in between. This has been shown to be a possible replacement for the commercial pressure sensors with limited resolution. We have built a new e-Cone prototype with a redesigned sensor. The redesigned sensor has a resolution of 128x64 sensor pixels to increase the sensor area and allow better enclosure of the casing. The readout circuitry has been redesigned to allow for a higher sampling rate. A battery with charging system is included to make the device completely wireless. The user interface has been given a responsive design with increased functionality. The pressure sensor is capable of visualising the grip pattern of a hand. We have explored the possibilities of image processing on both the server and client side. With client-side interpolation, we are able to achieve a frame rate of 15 frames per second at a resolution of 512x256. |
