Self-sensing intelligent microrobots for noninvasive and wireless monitoring systems

This paper introduces a novel self-sensing AI microrobot capable of wireless, real-time signal transmission and environmental response without an onboard power supply. The microrobot interacts with external electromagnetic imaging equipment, enhancing the local radiofrequency (RF) magnetic field to achieve high-resolution, deep penetration sensing. Its operational range is determined by the sensor circuit structure, with environmental conductivity and permittivity modulating the enhancement effect (up to ~560 times). Guided by an external magnetic field, the microrobot's magnetic tail enables precise movement, promising minimally invasive in vivo monitoring, particularly around disease sites, for early diagnosis. The fabrication process allows for the production of microrobot swarms.
