Using our muscles to control things is how most of us are accustomed to doing it. Sparkfun push buttons, pull levers, move joysticks... but what if Sparkfun could take the buttons, levers, and joysticks out of the equation and control it with our muscles? The MyoWare® 2 Muscle Sensor is an Arduino-compatible, all-in-one electromyography (EMG) sensor from Advancer Technologies that allows you to do just that! The MyoWare 2 Muscle Sensor has been redesigned from the ground up with a new, easy-to-use, compact design and upgraded with the latest and greatest chipset, improving sensor performance and reliability. The innovative snap connector system eliminates the need to solder connections for the MyoWare 2 ecosystem. It's easy: stick on a few electrodes (not included), read the output voltage, and flex some muscles!
The MyoWare 2 Muscle Sensor 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). MyoWare 2 has improved resistance to ground loops caused by wall-powered applications and/or noisy power supplies (for example, some switching USB supplies).
The harder you flex, the more motor units are recruited to generate great muscle force. The greater the number of motor units, the more the electrical activity of your muscle increases. MyoWare 2 Muscle Sensor will analyze a muscle's filtered and rectified electrical activity and output a signal (0-VIN volts, where VIN signifies the voltage of the power source) that represents how hard the muscle is being flexed.
The MyoWare 2 Muscle Sensor builds upon its previous wearable design that allows you to attach biomedical sensor pads directly to the board itself, removing those pesky cables. This board includes a single-supply voltage of +3.3V to +5V, three output modes, reverse polarity protected power pins, and indicator LEDs. Additionally, Sparkfun have developed a few shields (such as the Cable, Power, and LED shields) that can attach to the MyoWare 2 Muscle Sensor to help increase its versatility and functionality! The muscle sensor’s snap connector system makes it easier to stack shields together. The top side connectors link to power and the sensor’s EMG envelope output, while the bottom links to the input electrodes.
Measuring muscle activity by detecting its electric potential has traditionally been used for medical research. However, with ever-shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into all kinds of control systems, such as video games, robotics, and prosthetics! Biomedical sensor pads can be purchased separately and are found in the Recommended Products section below.
