About

Yuanqiang Song is a leading figure in flexible electronics and advanced dielectric materials, with a focus on developing next-generation wearable sensors. His research centers on enhancing the piezocapacitive effect—a key mechanism for pressure sensing—by engineering novel composite structures. In his highly cited 2017 work (68 citations), Song first proposed a groundbreaking strategy to dramatically improve sensor sensitivity by constructing a porous dielectric layer composed of CaCu₃Ti₄O₁₂–polydimethylsiloxane (CCTO-PDMS) composite sponges. This innovation enabled the creation of an ultrasensitive flexible capacitive pressure sensor, demonstrating exceptional performance for applications in wearable electronics and human-machine interfaces. By theoretically and experimentally validating the role of the porous structure in amplifying the piezocapacitive response, Song’s work has provided a foundational design principle for the field. His contributions have significantly advanced the sensitivity and practicality of flexible pressure sensors, influencing subsequent research on porous dielectric composites for soft robotics, health monitoring, and smart textiles.
