▎ 摘　　要

NOVELTY - Flexible antenna sensor comprises a substrate 12 and a radiation layer 13 arranged on the substrate, where the surface of the substrate away from the radiation layer is provided with a ground layer 11 and the material of the radiation layer includes a two-dimensional layered material. USE - Flexible antenna sensor for monitoring human health data such as heartbeat, pulse and blood oxygen content. ADVANTAGE - The flexible antenna sensor changes its resonant frequency when the antenna sensor is strained to directly obtain accurate strain information without external circuit, thus resulting in a larger volume of the flexible sensor and is prepared in simple and rapid manner at low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the flexible antenna sensor, which involves: a. providing two-dimensional layered materials and substrates; b. preparing a dispersion liquid containing the two-dimensional layered material, coating the dispersion liquid on the substrate, and performing drying treatment to obtain the radiation layer; and c. bonding the ground layer to the surface of the substrate away from the radiation layer. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of the flexible antenna sensor. Ground layer (11) Substrate (12) Radiation layer (13) Radiation unit (131) Feeder unit (132)
