Abstract
The primary
pathway for the transmission of motor control information between the brain and
muscle is through the peripheral nerves. Volitional motor control can be
provided to a user at any level of the motor control pathways by using numerous
technologies. One method is to record activity from peripheral nerves in the
residual limb using longitudinal interfascicular electrodes (LIFEs). This
method has an ultra-low amplitude, broad shape, and low signal-to-noise ratio. Although
there have been many advances in prosthetic technology, existing systems are
limited in restoring function after limb loss. FIU researchers
have invented a circuit and circuit system that can record activity such as
peripheral nerve activity. The design of the system combines a shared
operational transconductance amplifier recording system architecture with
differential input series-connected transistors, resulting in a reduction of
power and size consumption. The invention is fully implantable, can be powered
wirelessly, and has good noise characteristics.
Benefit
· A circuit and circuit system with good noise characteristics, low power consumption, and low area · Implantable circuit and circuit system
Market Application
The circuit and circuit system are useful to record activity from peripheral nerves to decode motor intent for seamless volitional control of prostheses and other related recordings of peripheral nerve activity or brain activity.
