Abstract:Muscle
spasm affects the hand rehabilitation of the person after stroke. This
paper presents the muscle temperature sensing and control with a
wearable device. The device mainly consists of three layers, i.e. a
Graphite heat dissipation film, a Peltier array, tailor-made radiation
fins, from bottom to top. Multiple temperature sensors PT1000 installed
between the film and the Peltier pieces are employed for distributed
detecting the surface temperature of the muscle which drives the motion
of fingers. The Peltier array is used to control the temperature of the
muscle with a PID controller for regulating the voltage supplied for the
Peltier array. The direction of the current through the Peltier array
can be adjusted for cold and heat stimulation of the muscle. By
precisely controlling the temperature of the muscle, this device could
alleviate the muscle spasm and reduce the edema of hand for better
rehabilitation treatment after stroke. The device can also be used for
investigating other symptoms alleviation needing cold stimulation or
thermotherapy.
