Frequently Asked Questions

Why Electromyography with FlexVolt?

The FlexVolt project started with a desire to alter human-machine interaction.  The initial prototypes were developed with the goal of providing an intuitive new way to interact with computers via muscle signals.  However, after many product demos and interactions with physical therapists, it became clear that the best application of FlexVolt EMG sensors is in physical therapy biofeedback, particularly for home-use cases.

Aren’t there already systems for measuring these signals?

Electromyography is not new, but the currently available systems are complex and expensive and usually only seen in medical centers or research laboratories.  FlexVolt breaks those barriers to make EMG and biofeedback accessible to everyone.  The FlexVolt is a first attempt at reaching a loftier goal – making biomedical technology affordable and available for in-home use.

How does FlexVolt compare to other low-cost EMG sensors?

The Myotrac EMG sensor is one of the only other home-use biofeedback sensors on the market.  It offers feedback via sound or LEDs, but does not interface with mobile devices.  At $500 for a single-channel sensor, it is significantly more expensive than FlexVolt.

Is it Safe?

Yes.  FlexVolt sensors are battery powered, and the sensor circuitry is automatically disconnected when charging the battery.  This means that there is never a potential for electrical connection between the patient and building power sources.

Will FlexVolt Devices be registered with the FDA as medical devices?

Yes.  The long-term plan is to register with the FDA to provide assurances for physicians and patients alike that FlexVolt is safe, reliable, and effective.
