Tindie Weblog | uMyo: Wi-fi EMG System


EMG, or electromyography, is a method for measuring electrical muscle alerts. It may be used for diagnostics, and such alerts can be utilized to manage prostheses or different units. Whereas a seemingly unique approach, experiments correlating electrical energy and muscle motion have been happening for over a century. In the event you’d prefer to strive your hand (activating muscle mass) at electromyography, then the uMyo wi-fi EMG gadget by Final Robotics offers the instruments to get you began.

The gadget 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 gadget transmits muscle inputs wirelessly and may 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 units could be connected to the identical arm to learn completely 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 may very well be mixed for gesture detection or one other utilization as desired.

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