GENERAL DESCRIPTION
Muscle activation is triggered by
bioelectrical signals of very low amplitude
sent from motor control neurons on our
brain to the muscle fibers.
Electromyography (EMG) enables the
translation of these electrical signals into
numerical values, enabling them to be used
in a wide array of applications. Our sensor is
especially designed for surface EMG, and
works both with pre-gelled and most types
of dry electrodes. The bipolar configuration
is ideal for low-noise data acquisition, and
the raw data output enables it to be used for
human-computer interaction and biomedical
projects alike.
