First Claim
1. An actively-powered temperature data logger patch with wireless data communication, comprising:
- a first substrate layer;
a sealed, flexible battery configured to provide continuous electrical power, comprising a printed electrochemical cell with an anode and a cathode, at least one of said anode and cathode being formed of a cured or dried ink, and first and second battery electrode contacts that are each electrically coupled to one of the anode and cathode;
a flexible circuit comprising a microprocessor, a temperature sensor configured to sense a temperature of a target subject, a wireless communication transceiver 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 electrode contacts to thereby electrically power the microprocessor and temperature sensor,wherein the microprocessor and the temperature sensor actively receive continuous electrical power from the flexible battery irrespective of whether the communication transceiver is powered,wherein the microprocessor further comprises a timer that actively receives electrical power from the flexible battery and is configured to enable the microprocessor to continuously obtain a plurality of temperature samples from the temperature sensor at a periodic time interval; 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 together comprise an electronics inlay that is arranged in a covering, stacked arrangement between the first and second substrate layers, andwherein all of the first substrate layer, electronics inlay, 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 inadvertent removal of the temperature data logger patch from the target subject.

Abstract
An actively-powered temperature data logger patch with wireless data communication includes a sealed, flexible battery comprising a printed electrochemical cell with an anode and a cathode, and a flexible circuit including a microprocessor, a temperature sensor configured to sense a temperature of a target subject, a wireless communication transceiver and an antenna. In one example, the flexible battery and flexible circuit are arranged in a covering, stacked arrangement between first and second substrate layers, and the patch configured to conform to a curved surface of the target subject. In another example, the patch is used in an actively-powered medical system for monitoring a body temperature of a patient, and includes an adhesive configured to be removably applied to skin of the patient. An external computing device is capable of two way communication with the wireless communication transceiver of the patch via an electromagnetic field.
