ABSTRACT:
The entropic echinoid 2 applies force to an object 6 with the cummulative effect of myriad feet 8 activated by fluid expansion pulses from electrical resistance heaters 30. Each heater lying in a fluid filed socket 10 of a substrate 4 and activated by a signal from a corresponding foot position sensing capacitor 26. The entropic echinoid is useful in high temperature environments for motors, actuators, bearings and clutches.
