uMyo - wearable EMG sensor

uMyo is a single channel wearable EMG sensor with wireless data transmission. Multiple sensors can be connected to one receiver. uMyo is a flexible EMG system allowing to pick up signals from different muscles - and not only from arms, but also legs, torso or even face. It is certified open source hardware (https://certification.oshwa.org/ua000003.html)

Main features of uMyo are:

• It’s wireless! No more mess of wires when working with EMG
• Works with any Arduino via nRF24 radio module (you can use our Arduino library)
• Works with ESP32 with no extra hardware (we also wrote an Arduino library)
• Multiple units (up to 12 in current version) can send data to the same Arduino/ESP32
• Sends out detected muscle activity level, 4-bins spectrum; and raw EMG data (in nRF24 mode)
• Can be used with a bracelet and dry electrodes, or with gel electrodes via soldered connector
