Using our muscles to control things is the way that most of us are accustomed to doing it. We push buttons, pull levers, move joysticks... but what if we could take the buttons, levers and joysticks out of the equation and control them with our muscles? The MyoWare® 2.0 Muscle Sensor is an Arduino-compatible, all-in-one electromyography (EMG) sensor from Advancer Technologies that allows you to do just that! The MyoWare 2.0 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 2.0 ecosystem. It's that easy: stick on a few electrodes (not included), read the output voltage and flex some muscles!
Our stock is the updated v2.0.4 (or later) version which has resolved potential issues in relation to a low-impedance path.
The MyoWare 2.0 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 fibres that generate the force behind your muscles).
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 2.0 Muscle Sensor will analyze the filtered and rectified electrical activity of a muscle 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 2.0 Muscle Sensor builds upon the previous wearable design that allows you to attach biomedical sensor pads directly to the board itself, getting rid of 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, we have developed a few shields (such as the Cable, Power, and LED shields to name a few) that can attach to the MyoWare 2.0 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 side links to the input electrodes.
Measuring muscle activity by detecting its electric potential has traditionally been used for medical research. However, with the advent of 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 found in the Recommended Products section below to be purchased separately.
Note: MyoWare and the Muscle Sensor 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.
