Electromyography (EMG)

Wearable Sensing’s DSI EMG are dry electrode sensors that have a wired connection directly to the DSI-24, DSI-7, or DSI Flex system. The sensors can be placed on the body, and used to detect the electrical activity of the muscles

Introduction

EMG, or Electromyography, is a technique for recording and interpreting the electrical activity of groups of muscles at rest and during activity. Electrodes can be placed anywhere on the body, such as the arms or legs, which are used to detect the electric potential generated by muscle cells. EMG can be used to detect muscle abnormalities, activation level, recruitment order, or to analyze the biomechanics of movement.

DSI Electrode Types

Wet Electrodes

DSI EMG can be equipped with snap-on sticky electrodes that can be easily placed anywhere on the body

Dry Electrodes

DSI EMG can be equipped with snap-on dry electrodes that can be secured on the body with a provided velcro harness

Wet Electrodes

Dry Electrodes + Harness

Applications

Compatible DSI Systems

DSI Flex

The DSI Flex has 7 customizable sensor locations, which can be configured in any variation of ExG, GSR, RESP, and TEMP

DSI-24​

The DSI-24 has 3 auxiliary inputs on the headset, allowing seamless integration of wired ExG, GSR, RESP, and TEMP

DSI-7

The DSI-7 has 7 EEG sensors, and 2 earclip references. These earclips can be modified to record ExG
