英文摘要
DESCRIPTION (adapted from the Investigator's abstract): In order to reanimate a
paralyzed limb to produce clinically useful movements, three functions must be
provided: 1) Electrical stimulators to cause muscles to contract; 2) A
controller to coordinate the stimulation; and 3) Sensors of command and
feedback signals from the patient to the controller. The investigators have
recently completed development and preclinical testing of a novel stimulation
technology that permits large numbers of individual muscles to be precisely
controlled by injectable, wireless microstimulators that receive power and data
by RF transmission from an external controller. They propose to extend that
technology by incorporating and testing various types of sensors in similar
injectable modules. These will use a novel, compatible system for RF
back-telemetry to send signals out of the limb for command and feedback
purposes. Their immediate goal is a family of generic "BIONs" (bionic
neurons)-that can be configured flexibly to serve a wide range of Functional
Electrical Stimulation (FES) applications. The investigators have selected the
following basic sensing modalities: 1) Low-level bioelectric signal recording
such as electromyography, to monitor (the) level of electrical recruitment
(M-waves) and spontaneous activity from muscles with some remaining voluntary
control (useful as myoelectric commands for prostheses);and 2) Triangulation of
relative position between devices, to be used for determining limb posture
Acceleration and inclination (vs. gravity), using microelectromachined silicon
(MEMS) sensor technology. The research will proceed in overlapping stages, the
first of which is already underway in pilot work: 1) Design, build and test the
basic circuit functions for low-level, low-power signal detection, digitization
and telemetric transmission; 2) Design, build and test specialized MEMS
sensors; 3) Build complete injectable BIONs with sensing and back-telemetry
capabilities; 4) Perform preclinical tests of sensor BIONs for
biocompatibility; 5) Test sensing and telemetry functions in vitro with
artificially-generated inputs; and 6) Test sensing and telemetry functions in
alert, behaving animals.
