GENERAL DESCRIPTION
Muscle activation is triggered by bioelectricalsignals of very low amplitude sent from motor
control neurons on our brain to the muscle
fibers. Electromyography (EMG) enables thetranslation of these electrical signals into
numerical values, enabling them to be used
in a wide array of applications. Our sensor isespecially designed for high performancesurface EMG data acquisition even in themost extreme conditions. The bipolar
configuration is ideal for uncompromised lownoise data acquisition, and the raw data
output provides medical-grade data enabling
it to be used for advanced and highly
accurate biomedical research. Examples:Fig. 1. Integrated miniaturized sensor + cable assembly
providing unrivalled headache-free use.

1 The number of bits for each channel depends on the resolution of the Analog-to-Digital

Converter (ADC); in biosignalsplux the default is 16-bit resolution (𝑛 = 16), although 12-bit(𝑛 = 12) and 8-bit (𝑛 = 8) may also be found.
