Abstract
FIU inventors
are designing and developing a system that will enhance the level of
functioning provided by prosthetic limbs. Commercially available prostheses
employ electromyogram (EMG) signals recorded from muscle tissues in residual
limbs in order to infer motor intent of the user.Continuing
research and development has shown that peripheral nerve activity of human
amputees can serve as an alternative to EMG signals. Peripheral nerve activity
can be recorded using longitudinal intrafasicular electrodes (LIFE) in order to
provide control of a one degree of freedom robotic arm.FIU inventors
are interested in using LIFEs to record peripheral nerve activity in order to
provide multiple degrees of freedom control of prostheses. A task that has not
been achieved by any of the methods developed so far.
Benefit
Allows for real-time operationImplemented in a portable, low power configurationCapable of interpreting signals from a single or multiple electrodes enabling single or multiple degree of freedom control of a powered prosthesisCapable of decoding neural activity in which the intended motor action consists of the intended class of action and the intended degree of action
Market Application
Control of neural prostheses and neural driven appliancesAbility to use decoded signals to interact with virtual environments (e.g. computers)Neural interfaces capable of recording nerve activity for control of prosthesesA model system to assess motor and neuron function during nerve stimulation and regional anesthesia applicationAs a means to decode electromyogram (EMG) and electroencephalogram (EEG) activity for the purpose of control of powered appliances
