Wearable patch and charging thereof and wireless booster station

Abstract

A wearable patch includes a stretchable and permeable substrate, a temperature sensing unit mounted in the stretchable and permeable substrate, wherein the temperature sensing unit includes a first electrode configured to contact a user's skin, and a temperature sensor in thermal contact with the temperature sensor and configured to measure the user's skin temperature. The wearable patch includesa second electrode and a third electrode respectively attached to the stretchable and permeable substrate, a circuit substrate on the stretchable and permeable substrate, and a battery configured to supply power to the control circuit and the temperature sensor. The control circuit can select a first mode for measuring a user's skin temperature and a second mode for charging the battery by the charging station via the first electrode, the second electrode, and the third electrode.

Problems solved by technology

[0009] Despite recent development efforts, current wearable patches still suffer from several disadvantages: they may not provide sufficient comfort for the user to wear them; they may not remain attached to the user for the desired length of time; and they're often not aesthetically appealing

[0010] Conventional wearable thermometer patches have additional challenges such as inaccurate temperature measurements caused by thermal resistance between the temperature sensor and human skin, conduction losses from the temperature sensor to the surrounding environment, and thermal conduction to the wearable patch. The temperature of the user's skin drops

Also, conventional wearable thermometer patches may have slower measurement response

[0011] Another downside of some conventional wearable patches is that they contain batteries that charge via a USB cable

This method of charging is inconvenient when the user is not near a power source such as a power outlet or laptop

[0012] Also, some conventional wearable patches have limited wireless communication range because their compact size often constrains the functionality of the on-board batteries and amplifiers
