Abstract

Shape-morphable microrobots can adapt their morphology to changingenvironments and tasks. However, monitoring their shape remains asignificant challenge. Here, we present a thermoresponsive magneticmicrorobot integrated with flexible radio-frequency (RF) electronics forwireless shape sensing. The microrobot consists of a thermoresponsivemagnetic hydrogel, an anisotropic mechanical support structure, and anembedded flexible dipole antenna. Temperature-induced actuationreversibly transforms the microrobot between helical and planarconfiqurations while maintaining magnetic actuation. The resultingchange in antenna geometry produces distinct RF responses that enableremote identification of the microrobot's shape. This work demonstratesa simple and robust strategy for integrating flexible electronics into softmicrorobots, providing wireless shape feedback for future adaptive andclosed-loop microrobotic systems.

Biography

Prof. Dr. Minsoo Kim is currently an Assistant Professor in theDepartment of Robotics and Mechatronics Engineering at DGIST. Hereceived his B.S. in Mechanical Engineering from Hanyang University(2012) and his Ph.D. in Mechanical and Aerospace Engineering fromSeoul National University (2018). He then became a Postdoctoral Fellow(2018-2020) at the Soft Robotics Research Center at SNU. Following this,he worked in the Multi-Scale Robotics Lab of the Institute of Roboticsand Intelligent Systems at ETH Zurich as a Senior Researcher (2020-2026). Dr. Kim' s research focuses on developing medical microrobotsthrouah the intearation of smart materials,micro-/nanoscaleengineering, and bio-interfacing technologies. By bridging systemintearation and material science, his research aims to advancebiomedical applications such as neuromodulation and targeted drugdelivery. He has published over 44 peer-reviewed journal articles atNatureCommunications, Science Robotics, AdvancedMaterialsAdvanced Functional Materials, ACS Nano, Small, Advanced OpticalMaterials, CIRP Annals, etc. He has served as a Research Affiliate of CIRP(The International Academy for Production Engineering) from 2019 to2023.
