Myowear 2.0
MYOWARE 2.0 Muscle Sensor measures muscle activity through the electric potential of the muscle, commonly referred to as surface electromyography (EMG or sEMG for short)
Features
Supply Voltage:
min. = 2.27V,
typ. = +3.3V or +5V,
max. = +5.47V
Input Bias Current:
250 pA, max 1 nA
Input Impedance:
800
Common Mode Rejection Ratio (CMMR):
140 dB
Ideal Gain Equation:
Raw (RAW): G = 200
Rectified (RECT): G= 200
Envelope (ENV): G = 200 * R / 1 kOhm
R is the resistance of the gain potentiometer in kOhm
