High-Density Flexible Hybrid-Integrated Temperature-Magnetic Sensing Array

To address the demand for high-density, curved conformal sensing in wearable devices and flexible electronic skin, this paper presents a novel flexible dual-modal sensing array capable of synchronous detection of temperature and magnetic field distributions. We detail the design principles, circuitry, and layout of the core sensing chip. A flexible hybrid integration scheme ensures device flexibility, with single-point tests confirming its excellent dual-modal sensing performance. Mounted on a robotic hand, the array demonstrates simultaneous monitoring of tactile stimuli and environmental temperature. Furthermore, the 6×6 array successfully achieves spatial distribution imaging of both magnetic fields and temperature. This technology holds broad application prospects in human-machine interaction, health monitoring, and robotic tactile perception.
