How it Works


The harder you flex, the higher the output voltage

The MyoWare measures muscle activity through the electric potential of the muscle, commonly referred to as surface electromyography (EMG or sEMG for short). When your brain tells your muscle to flex, it sends an electrical signal to your muscle to start recruiting motor units (the bundles of muscle fibers that generate the force behind your muscles).

The harder you flex, the more motor units are recruited to generate greater muscle force. The greater the number of motor units, the more the electrical activity of your muscle increases.

The MyoWare will analyze this electrical activity and output an analog signal that represents how hard the muscle is being flexed. The harder you flex, the higher the MyoWare output voltage will go.

MyoWare FAQs


 

Q: Can MyoWare be used in medical applications?
A: No, MyoWare sensors are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation treatment, or prevention of disease, in a man or other animals.

Q: How can I avoid any electrical interference when using MyoWare 2.0?
A: In order to avoid causing any accidental damage to your MyoWare 2.0 boards, it is imperative that you do not power the boards, or the computer programming them, via a wall adapter. Please be sure to one use a battery when powering MyoWare 2.0.

Q: Why was MyoWare redesigned?
A: MyoWare 2.0 originated with the intent to provide users with a more user-friendly design in order to avoid any electrical discharge while also increasing contacts with the body that will supply you with more accurate readings.

Q: How do I attach MyoWare 2.0 to my body?
A: Great question! The innovative snap connector system eliminates the need to solder connections for the MyoWare 2.0 ecosystem. It's that easy: stick on a few electrodes (not included), read the output voltage and flex some muscles!
