Tindie Weblog | uMyo: Wi-fi EMG System


EMG, or electromyography, is a way for measuring electrical muscle indicators. It may be used for diagnostics, and such indicators will also be utilized to regulate prostheses or different gadgets. Whereas a seemingly unique method, experiments correlating electrical energy and muscle motion have been occurring for over a century. In case you’d wish to attempt your hand (activating muscle mass) at electromyography, then the uMyo wi-fi EMG machine by Final Robotics gives the instruments to get you began.

The machine takes the type of a circuit board, held in place through an athletic strap wrapped round your forearm, or presumably your higher arm and even leg with a little bit of stretching and/or modification. The circuit board measures muscle inputs utilizing the included gel or dry electrodes, and the system’s snap connectors can be utilized to use moist electrodes as effectively.

The machine transmits muscle inputs wirelessly and might work with an ESP32 with out extra {hardware}. Arduino-style boards can be utilized with the addition of an nRF24 radio module. A number of gadgets might be hooked up to the identical arm to learn totally different muscle group inputs, and as much as 12 gadgets can talk wirelessly with a single Arduino/ESP32. With correct processing, an array of sensor inputs could possibly be mixed for gesture detection or one other utilization as desired.

You may see it in motion within the video beneath, utilizing two sensors in tandem. For more information on this venture and its improvement, try the uMyo venture go surfing Hackaday.io.
