Product Overview
We are accustomed to interacting with the world through physical inputs, such as pushing buttons, pulling levers, and moving joysticks. But what if you could remove the controller entirely? The MyoWare® 2.0 Muscle Sensor allows you to control your projects using the electrical signals naturally generated by your body. Whether you are building a robotic prosthetic, designing a custom video game controller, or exploring biomechanics, this all-in-one electromyography (sEMG) sensor makes it easier than ever to integrate muscle control into your builds.
Redesigned for a Solderless Experience
Built from the ground up by Advancer Technologies, the MyoWare 2.0 features an upgraded, highly reliable chipset packed into a compact, wearable design. Best of all, it features an innovative snap-connector system that completely eliminates the need for soldering within the MyoWare 2.0 ecosystem.
- Plug-and-Play Shields: Easily stack functional add-ons—like the Power, LED, and Link shields—directly onto the sensor's low-profile connectors in seconds.
- Say Goodbye to Messy Cables: The wearable board design lets you attach biomedical sensor pads directly to the sensor itself, eliminating tangled wires and reducing external signal noise.
How EMG Sensors Work
When your brain tells a muscle to flex, it recruits motor units that generate an electrical pulse. The MyoWare 2.0 Muscle Sensor detects this electric potential, analyzes the filtered and rectified activity, and outputs an analog signal (0-VIN) representing how hard the muscle is flexing.
- Broad Compatibility: Operates on a single-supply voltage of +3.3V to +5V, making it highly compatible with Arduino and other popular microcontrollers.
- Visual Feedback: Built-in indicator LEDs let you instantly monitor power status and signal activity, making troubleshooting a breeze.
- Safe and Protected: Designed with reverse polarity protected power pins to keep your board safe during rapid prototyping.
