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 sealed, flexible battery configured to provide continuous electrical power via first and second battery contacts;

    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 first and second battery contact pads that are each electrically coupled to one of the first and second battery contacts 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 battery to enable the microprocessor to continuously obtain a plurality of temperature samples from the temperature sensor at a periodic time interval,wherein the temperature sensor is located at the first end of the first substrate layer, and the antenna is located at the opposite second end of the first substrate layer; and

    a second substrate layer comprising an adhesive configured to be removably applied to a surface of the target subject,wherein the flexible battery and flexible circuit are disposed between the first and second substrate layers, and all of the first substrate layer, flexible battery, 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 battery, circuit, or active operation thereof.
