Abstract
Electromyography (sEMG) is the technique applied to measure the bio-potential signal produced by a contracting skeletal muscle. sEMG has been used for subject intention estimation, force estimation, limb angle estimation and determining muscle activation timing. Typically most sEMG devices on the market, and in literature, are not open source hardware. This results in a device that can be considered as a black box, as it is difficult to determine the applied signal processing. This paper presents an open source low-cost active sEMG circuit, allowing an understanding of sEMG and the challenges involved in designing a high quality device. An open source sEMG design reduces the time and cost associated with initial sEMG research, providing a larger number of researchers with the opportunity to utilise sEMG. The device has been tested on three subjects, resulting in a low baseline noise ⩽5.2μVrms and great line noise rejection, resulting in a sensitive device that can capture high quality bio-potential signals.
