Tindie Weblog | uMyo: Wi-fi EMG Gadget


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

The machine takes the type of a circuit board, held in place by way of 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 properly.

The machine transmits muscle inputs wirelessly and might work with an ESP32 with out further {hardware}. Arduino-style boards can be utilized with the addition of an nRF24 radio module. A number of units may be connected to the identical arm to learn totally different muscle group inputs, and as much as 12 units 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’ll be able to see it in motion within the video under, utilizing two sensors in tandem. For more information on this undertaking and its growth, take a look at the uMyo undertaking go online Hackaday.io.
