This week I added the capacitive touch sensors to the glove and presented at the interim demo. I was using conductive copper tape as the contacts for the glove, but I think it’s not a great long term solution since the adhesive can wear off and the copper gets crinkled. My solution is to embroider the glove with conductive thread to create a durable and flexible contact. My verification process involves confirming that the components work and can integrate effectively with the larger subsystems. Over the past few weeks I verified that the following components worked: flex sensors, IMU, ADS, capacitive touch sensor. First I confirmed that each component could be operated according to the manufacturer’s instructions by connecting it to a breadboard and measuring relevant information (ex: resistance, voltage with a multimeter). Then I connected it to the Pico and worked with Kat to make sure the signals were being received. Finally I attached the components to the glove and made sure signals were still accurate. For example, I first confirmed that the flex sensors worked as a voltage divider on a breadboard, then added it to a breadboard with the Pico. When I attached the flex sensors to the glove, the range of motion changed but data was still available, so I helped Kat calibrate the sensors to detect % finger bending. I believe the IMU data will need more calibration since the Z axis is very sensitive. We will also verify the gloves functionality after seeing the ML training data output.
