Claim 26:
27. An actuation system comprising:
a plurality of actuation devices, each actuation device comprising:
a plurality of spatially distributed actuators, each actuator configured for interacting with a biological skin surface;
a wireless controller configured to receive operative command signals to control each of the actuators;
a wireless power system to power the actuators; and
a flexible substrate that supports each of the actuators, the wireless controller and the wireless power system; and
wherein each actuation device is in wireless communication with at least one other actuation device; and
wherein the wireless controller operably controls the plurality of spatially distributed actuators by electrically energizing at least one individual actuator at a time with the other actuators in an off-state and cycling through all actuators at a switching frequency.
