EMG Home Trainer

摘要

A system for the detection, recording, and analysis of EMG data attained during exercise in real-time is described. The system employs a surface EMG sensor equipped with a Bluetooth or a Wi-Fi module. The sensor transmits sEMG data via Bluetooth or Wi-Fi to a smart device, which processes this data utilizing a preloaded application and informs the user of the efficacy of exercises with key statistics in real-time. A sensor box containing the EMG sensor also contains a pre-amplification circuit, an amplification circuit, a DC-offset circuit, and a signal smoothing and amplifier circuit to maximize the reduction of extraneous noise frequently observed with conventional sEMG sensors. A proprietary mobile device application receives, interprets, records, and displays the EMG data for the user.

主权项

1. A system for monitoring muscle activity in real-time during exercise from a mobile device comprising:
a sensor box, said sensor box equipped with a top portion and a bottom portion; a first silver prong, said first silver prong disposed on said bottom portion of said sensor box; a second silver prong, said second silver prong disposed on said bottom portion of said sensor box; a third silver prong, said third saver prong disposed on said bottom portion of said sensor box; a fourth silver prong, said fourth saver prong disposed on said bottom portion of said sensor box; a power supply; wherein said second silver prong and said third silver prong are configured to detect surface EMG potential, producing analog signals; wherein said first silver prong and said fourth silver prong are grounds; a pre-amplifier circuit, said pre-amplifier circuit providing a first output of said analog signals; wherein said pre-amplifier circuit is disposed within said sensor box; an amplification circuit, said amplification circuit disposed within said sensor box; wherein said amplification circuit is configured to magnify said first output of said analog signals, providing a second output; wherein said amplification circuit is configured to filter said analog signals of extraneous noise; wherein said amplification circuit is configured to convert said analog signals to digital signals; a DC-offset circuit, said DC-offset circuit configured to off-set the output of a signal smoothing and amplifier circuit, said signal smoothing and amplifier circuit receiving said pre-amplifier circuit output and said de-offset circuit output; a CMOS operational amplifier, said CMOS operational amplifier configured to combine said output of said pre-amplifier circuit with said output of said DC-offset circuit to a smoothed and amplified output of EMG data; a wireless transmitter, said wireless transmitter configured to convey said smoothed and amplified output wirelessly to the mobile device; an application, said application running on the mobile device; and wherein said application stores, interprets, and displays said EMG data to the user via a screen of the mobile device.
