THERAPEUTIC PRESSURE SYSTEM

摘要

A therapeutic pressure system includes a sealed actuator housing containing an electrolyte and one or more polymer actuators that actuate via movement of electrolyte components into, out of, around or within the polymer matrix of the polymer actuators. The system also includes an actuator support structure for the polymer actuators, working and counter electrodes in working contact with the actuators, circuitry for connecting the electrodes to a power source, and a controller between the power source and the electrodes to control the electrical current to the electrodes. The system is particularly useful for use in a hospital bed.
