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 high performance
surface EMG data acquisition even in the
most extreme conditions. The bipolar
configuration is ideal for uncompromised low-
noise data acquisition, and the raw data
output provides medical-grade data enabling
it to be used for advanced and highly
accurate biomedical research. Examples:
