1. A virtual reality device comprising:
a plurality of spatially distributed biologically interactive devices configured for interacting with a biological surface, each of the biologically interactive devices comprising: a sensor and an actuator;
a wireless controller configured to receive operative command signals to control each of the biologically interactive devices and transmit to a remote controller output from each of the sensors; and
a wireless power source operably connected to the plurality of biologically interactive devices,
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.
