Abstract

The invention discloses a wireless pressure sensor and a manufacturing method thereof. The wireless pressure sensor comprises a fabric partition; one side of the fabric partition is provided with a plurality of passive antennas arranged in an array, and the other side of the fabric partition is provided with a plurality of ferrite films; and the ferrite films are arranged in one-to-one correspondence with the passive antennas, and the positions are aligned with each other. The invention can centralizedly absorb the magnetic energy from the passive antennas through the ferrite films, thereby effectively improving the sensitivity of the device and avoiding interference of conductive materials.

Description

technical field [0001] The invention relates to a wireless pressure sensor and a manufacturing method thereof, belonging to the technical field of sensors. Background technique [0002] The development of electronic textiles is an active research field in biomedicine and robotics. Devices based on this technology have great physical flexibility, excellent wear resistance, and are easy to integrate with various fabric substrates, which are traditional electronic materials. equipment cannot achieve. E-textile pressure sensors have been used in various applications such as: wearable health monitoring, smart home care, medical diagnosis, and human motion detection. Sensors based on different sensing mechanisms based on capacitive, resistive, and piezoelectric measurements have been introduced to develop e-textiles. For example: R. Li et al. developed a fabric-based capacitive pressure sensor by assembling a flexible ion-conducting polymer sandwiched between two layers of condu...
