Outline of Final Research Achievements

We have developed and improved the sensors several iterations. In each, the sensor's performance was improved. Currently, the temperature of the sensor is reduced to 45 degrees. Moreover, it has been proven that the sensitivity of the sensor can be adjusted. This can be very beneficial when only 1 type of sensor are to subject to various range of force. The sensor has been improved to utilize the measurement range of the chip we used in the sensor effectively. We found that we can still improve the sensor to cover more of the measurement range. We plan to improve the sensor further and integrate the sensor into a big patch which to be installed on a robot.
