Claim:
1. An actively-powered temperature data logger patch with wireless data communication, comprising: a first substrate layer comprising a first end and an opposite second end; a plurality of sealed, flexible batteries in a parallel arrangement and configured to provide continuous electrical power, each battery comprising a printed electrochemical cell with an anode and a cathode that are provided in a co-planar arrangement and an aqueous electrolyte layer covering and in electrical contact with said anode and cathode; a flexible circuit comprising a microprocessor, a temperature sensor configured to sense a temperature of a target subject, a wireless communication transmitter and an antenna, the flexible circuit further comprising a plurality of contact pads that are electrically coupled to corresponding contacts of the plurality of flexible batteries to thereby electrically power the microprocessor, wireless communication transmitter, and temperature sensor, wherein all of the microprocessor, temperature sensor, and wireless communication transmitter actively receive electrical power from the flexible batteries to enable the microprocessor to continuously obtain a plurality of temperature samples from the temperature sensor at a periodic time interval; a second substrate layer comprising an adhesive configured to be removably applied to a surface of the target subject, wherein the flexible batteries and flexible circuit are disposed between the first and second substrate layers, and all of the first substrate layer, flexible batteries, flexible circuit, and second substrate layer are sufficiently flexible so that the temperature data logger patch is configured to conform to a curved or variable surface of the target subject and is able to flex and move together with movement of the target subject without degradation of the batteries, circuit, or active operation thereof; and a switch used to activate the microprocessor to an operational power state and thereby enable said active electrical power to the microprocessor, temperature sensor, and wireless communication transmitter only when a user intends to begin use of the patch.
