Ultraflexible magnetic sensor system integrated with organic multifunctional circuits

Abstract

In this presentation, we report an ultraflexible magnetic sensor matrix system comprising a 2 × 4 array of magnetoresistance sensors, a bootstrap organic shift register driving the matrix, and organic voltage amplifiers integrated within a 3-µm-thick polymer substrate. The system demonstrates high magnetic sensitivity owing to the use of organic amplifiers. Moreover, the shift register enabled real-time mapping of 2D magnetic field distribution. These ultraflexible magnetic sensor systems integrated with organic multifunctional circuits are suitable for use in position control systems used in applications such as soft robots, wearable electronics, and smart textiles.
