The invention provides a smart sensor (10) in the form of an adhesive bandage (32). The sensor (12) sticks to people and objects and wirelessly communicates with remote receivers (24). Internal detectors (12) sense conditions associated with movement or the environment of the sensor. Typically, sensors of the invention communicate by an RF transmitter or transceiver (16). Groups of sensors may be combined within a common canister that imparts date and time information and “power on” when dispensed.
