Abstract
This invention relates to biofeedback device, and more particularly to device for detecting, interpreting and recording the electrical field generated by the contraction of muscles and using the electrical field data to control an external device.
Claims20
A biofeedback device for processing an electrical signal generated by with the contraction of one or more muscles, the device comprising:
- a processor configured to for electrical communication with a sensor worn by a user, the processor including:
- a signal processing circuit for processing at least at least one of an electrocardiogram (EKG) signal and an electromyogram (EMG) signal received from the sensor;
- a selector switch for changing an amplification factor of the signal processing circuit;
- a microcontroller for receiving the processed signal from the processor, the microcontroller providing an output signal to an external device,
- wherein the output signal provides instructions for controlling at least one function of the external device.
2 more elements
A method of using a biofeedback device for directing the control of an external device, the method comprising:
- receiving an input signal at a processor from a sensor coupled to a user's skin, the input signal including at least one of an electrocardiogram (EKG) signal and an electromyogram (EMG) signal;
- processing the input signal at a signal processing circuit included in the device, processing the signal including applying an amplification and a filter to the input signal;
- receiving the processing signal at a controller and providing an output signal to the external device based on the processed signal, the output signal including instructions to the external device for controlling at least one function of the external device.
