Title:
PATCH-TYPE LIGHT-BASED HEALTHCARE DEVICE HAVING LIGHT-CONDENSING FILMS COMBINED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2024/075915
Kind Code:
A1
Abstract:
The present invention relates to a patch-type light-based healthcare device having light-condensing films combined therewith, in which a light-emitting part outputs light, a light-receiving part receives light outputted from a light output part, a spacer is provided between the light-emitting part and the light-receiving part so as to block the light outputted from the light-emitting part, and the light-emitting part and the light-receiving part each comprise at least one light-condensing film for condensing dispersed light, the light-condensing film of the light-emitting part having a plurality of concave lens-shaped first light-condensing surfaces in order to improve the penetration depth of light in skin tissue, the light-condensing film of the light-receiving part having a plurality of convex lens-shaped second light-condensing surfaces in order to increase the detection amount of light reflected from skin tissue, and the light-condensing films having poly(dimethylsiloxane) (PDMS) and a Norland optical adhesive (NOA) alternately laminated, thereby reducing the ratio of noise to the limited light output of the light-based healthcare device, and thus enabling the enhancement of light-receiving efficiency.
