WIPO Patent Application WO/2023/032884
Kind Code:
A1
Abstract:
A ring-type device (101) comprises a wireless power reception circuit, a radio communication circuit, and a ring-shaped structure (1). The wireless power reception circuit is composed of a power reception circuit and a loop coil. The radio communication circuit is a circuit that operates using the loop coil as an antenna. The power reception circuit and the radio communication circuit are composed of electronic components and a flexible circuit board on which the electronic components are mounted. The ring-shaped structure (1) has a ring side surface (1S), a ring upper surface (1T), and a ring lower surface (1B). The loop coil is formed in a position along the ring upper surface (1T). The flexible circuit board is a planar structure when deployed, and is disposed on and curves along the ring side surface (1S) of the ring-shaped structure (1).
