Surface EMG Sensors

Wireless / Wired (Integral Electrodes)

Unlock the power of precise muscle measurement with Biometrics Ltd. Surface EMG sensors, expertly designed for your convenience in both wired and wireless configurations. With input impedance greater than 100 Mohms, our sensors require minimal or even no skin preparation - saving you valuable time in your research and studies.

The DataLITE wireless EMG sensor is small, lightweight and uses progressive frequency hopping, error detection and data recovery algorithms, allowing muscle activity readings to be smooth and robust even in a typical work environment with a range of up to 30 meters from its receiver.

Amplifiers (Disposable Electrodes)

In areas where adjustable inter-electrode distance is necessary, our wireless LE230FW or wired SX230FW sensors stand out with their flexible design that is compatible with any reusable or disposable SEMG electrode incorporating a 4mm snap. The maximum inter-electrode distance is 170mm and the minimum distance is dependent upon the size of the electrodes used.

Frequently Asked Questions

The electrical activity generated by skeletal muscles is measured using electromyography (EMG) sensors, which are specialist instruments. When muscles contract and relax, electrically charged particles (ions) exchange within the muscle fibers, producing this electrical activity. The data may be processed to provide details about muscle activity after the EMG sensors have picked up and amplified the signals. This might contain specifics pertaining to the frequency and strength of muscular contractions, as well as muscle wear and tear.

We have high input impedance EMG sensors. As a result, they can measure muscle electrical activity precisely without using conducting gels or arduous skin preparation.

A high input impedance in an EMG sensor ensures accurate and reliable readings by reducing the loss of signal strength.

Our EMG sensors have undergone thorough testing and development to meet the rigorous requirements of muscle activity analysis. They offer high-quality data, incorporate recent design principles and technological advancements, and have features like variable gain and movable low-pass filters to meet particular research requirements.

The sensor itself has reusable integral electrodes that are built-in. On the other hand, single-use disposable electrodes can be changed out after each session.

Depending on your unique needs, you can choose between wired and wireless options. While the wired option might be better suited for studies that must remain stationary, the wireless option provides greater mobility and is ideal for such studies. Both provide superior data capture.

The range of frequencies that the sensor can precisely measure depends on its bandwidth. Our sensors have a broad bandwidth range, which gives them the flexibility to record various kinds of muscle activity.

The sensor's capacity to block unwanted signals is referred to as the CMRR (Common Mode Rejection Ratio). The sensor can better distinguish between muscle signals and noise when the CMRR is higher. Gain, which determines how much the sensor amplifies the muscle signals, is the amplification factor of the sensor. The resistance provided by the sensor to the flow of electrical current is referred to as input impedance. A higher input impedance results in more accurate measurements.

Users can modify the sensor's sensitivity to fit it to particular applications thanks to variable gain. Users can adjust the low pass filter's bandwidth to narrow the sensor's bandwidth and concentrate on their target frequencies.

We provide thorough customer service and a two-year warranty for our products.
