The Dry Electrode Single-Lead Myoelectric Sensor EMG is a high-quality and versatile sensor for measuring muscle activity. With its dry electrode design, this sensor offers a comfortable and hassle-free experience, eliminating the need for gels or adhesives. It also has a compact and user-friendly design, making it suitable for various applications, from medical research to sports performance tracking.

The sensor integrates the filter and amplification circuit, amplifies the weak electrical signal of human surface muscle within a range of 1.5mV, and effectively suppress the noise (especially the frequency interference) by differential input and analog filter circuit. The output Signal is in the form of analog, with 1.5 V as reference voltage and 0 to 3.0 V from the output. The magnitude of the output signal depends on the The amount of activity of the selected muscle, the waveform of the output signal can significantly indicate the condition of the subcutaneous Muscle situator in the sensed position, facilitate the analysis and examination of myoelectric signal, detect muscle activity, such as Muscle density, strength, fatigue, etc.

The dry electrode electromyography sensor is an active sensor that provides high quality signal collection and is easy to use. Or Used in static or dynamic applications, it takes only some extremely simple preparation. The use of dry electrode guide, no conductive Gel also can get good signal quality, so with long service life, easy and convenient to use and so on, more suitable for ordinary users, and using the medical electrode of the gel probe is usually disposable, more inconvenient to use.
