Flexible capacitive sensor based on Miura-ori structure

Hong Sun et al.

Summary: Flexible capacitive pressure sensors have been widely used in various applications, but maintaining sensitivity and performance under high stretching and increasing pressure remains a challenge. In this study, a Symmetrical Miura-ori Capacitive sensor (SMC sensor) was developed based on the Miura-ori structure to achieve a positive correlation between sensitivity and pressure within a tunable range. The SMC sensor showed high stability, a maximum sensitivity of 0.648 kPa-1, and the ability to detect both contractive and stretched strains. This sensor has great potential for general physiological signal monitoring under high stretching and environmental adaptability.
