Myoelectric sensors are devices that detect electrical signals generated by muscles when they contract. These signals are captured through electrodes placed on the skin, allowing the sensors to interpret muscle activity. This technology is commonly used in prosthetics, enabling users to control artificial limbs by simply thinking about moving their muscles. The data collected by myoelectric sensors can be processed and translated into movements for devices like robotic arms or hands. This allows for more natural and intuitive control, improving the functionality of prosthetic devices. Myoelectric sensors are also used in rehabilitation and assistive technologies to help individuals regain mobility and strength.
