Abstract: A stretchable substrate and a manufacturing method of the stretchable substrate are disclosed. In a step of manufacturing a flexible substrate, a circuit pattern composed of one or more mounting pad parts configured to cause electronic parts to be mounted to a polyimide film PI having a fixed size is formed, and a wiring pattern configured to circuit-connect the mounting pad parts is formed, and further an outer circumferential line of the circuit pattern is realized in a cutting line for cutting. In a step of mounting parts, the electronic parts are mounted on the circuit pattern of the flexible substrate. In a punching step for cutting the cutting line, a punching jig set to be aligned to the cutting line of the flexible substrate on which the parts are mounted is utilized, thereby realizing the excellent tensile performance of wiring configured to connect a circuit.

Abstract: The present invention provides a skin care diagnostic system characterized in that an LED light path is linked to a user terminal device having: a camera module for capturing an image of a skin surface; and a skin care service application generating control solution information of the LED light patch by analyzing the image captured by the camera module and an impedance measurement value received from the LED light patch. The LED light patch comprises: a BIA module for sensing the bioelectrical impedance of the skin surface; a BLE module for transmitting the impedance measurement value measured by the BIA module and receiving the control solution information of the LED light patch; a battery module comprising a thin-film battery; an LED module on which micro-LED devices are mounted in an array; and a control processor performing area-specific control, dimming control, wavelength control and user-selected care time control of the LED module in accordance with the received control solution information.
