Abstract

This paper presents a 3D-structured origami-based pressure sensor for wireless pressure monitoring. The sensor utilizes an inductor-capacitor (LC) sensor and a monopole antenna for wireless detection. A 3D-printed insole incorporating a Miura-ori origami design seamlessly integrates conductive 3D-printed sensors. Wireless monitoring of resonant frequency and intensity changes in the LC sensors enables foot pressure monitoring for various postures. The sensor's sensitivity is tunable, ranging from 15.7 to 2.1 MHz/kPa for pressure ranges of 0–9 kPa and 10–40 kPa, respectively. The platform shows potential for applications in orthotics, prosthetics, and sports gear.
