Electromyography sensor

Abstract

In view of the foregoing, an aspect herein provides an Electromyography (EMG) sensor (100) further includes electrodes (102) adapted to be attached to an external surface of skin of a limb, and configured to sense signals from the external surface of the skin, a first amplifier (108) connected to the electrodes (102), and configured to generate a first amplified signal based on a differential signal, existing in microvolts, associated with the electrodes (102), a second amplifier (112) connected to the first amplifier (108), and configured to generate a second amplified signal based on the first amplified signal, and a first filter (114) connected to the second amplifier (112), configured to reject high-frequency noise from the second amplified signal to generate an output signal and prevents interference by the electromagnetic interference from nearby electrical noise, false high-frequency signals and in-circuit internal electronic noise. An Electromyography (EMG) system (200) includes the EMG sensor (100) installed in an electronic device, a control circuitry (116) connected to the EMG sensor (100) and configured to control an operation of the electronic device based on the output signal.
