Flex sensor glove

thingiverse

These printable parts make up a flexible sensor glove that controls movements of a robotic prosthetic hand designed for a patient who lost his right hand in an accident. Surgery left the wrist intact, so standard prosthetics couldn't be used. We opted out of myo-electric input commands since they require signal amplification, and instead decided to replicate the movements of the left hand using this sensor glove. The Nintendo Power Glove inspired us to build a robotic prosthetic hand that can mimic the movements of a human hand. We built a voltage divider from the flex sensors so an Arduino Nano could read data from analog pins. Then, NRF24L01 transmits finger movements over WiFi to the hand, which is available at: https://www.thingiverse.com/thing:3771283. Use attached STLs to print cases for electronics and reinforce soldering on sensor connectors, which are very fragile. Videos of the hand in action can be found at the following addresses: Movement: https://youtu.be/9lCXrkcVzPw Tendons: https://youtu.be/tw_zP7BXp7E Writing: https://youtu.be/Fz-MuXwgLbw Grabbing a round object: https://youtu.be/AQXdd-NVf8E Grabbing an heavy object: https://youtu.be/TT7kAvTvNJQ Using the phone: https://youtu.be/0eBjgeCwozA Remote control: https://youtu.be/8eH8Bw6Lkv4 On the field: https://youtu.be/TUoOgagwnh8 To power electronics, you'll need five 2.2'' flex sensors, an Arduino Nano board, NRF24L01 boards, and a cell phone power bank. A detailed book about the hand's realization, building instructions, and the patient's case are available at http://www.sanditlibri.it/ or https://www.amazon.it/dp/8869283291/.
