▎ 摘　　要

NOVELTY - The healthcare device (100) comprises a heater (110) for generating heat corresponding to a preset temperature value at a location corresponding to the attachment portion. A substrate (120) is formed on the heater. A temperature sensing layer (130) is formed on the substrate, and senses a capacitance value corresponding to a temperature of the attachment portion. A control unit (140) calculates a temperature distribution of the attachment portion based on the sensed capacitance value. A lower transparent electrode (131) is formed on the substrate. A dielectric layer (132) is formed on the lower transparent electrode. The lower transparent electrode and the upper transparent electrode (133) are graphene, silver nanowires, indium tin oxide, indium zinc oxide, and carbon nanotubes. The dielectric layer is polymethyl methacrylate, polycarbonate, poly vinylidene fluoride, cyclic olefin copolymer, and aluminum oxide. USE - Healthcare device for monitoring biometric data, such as temperature, for disease diagnosis and prediction. ADVANTAGE - The healthcare device is capable of calculating a temperature distribution for an attachment site using a capacitive skin-attached temperature sensor, not a large and complex measuring units, such as an infrared thermal camera. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for operating a healthcare device. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a healthcare device.
