About

Kei Iwata is a pioneering researcher at the intersection of microelectromechanical systems (MEMS), biomimetic robotics, and hardware neural networks. His work focuses on creating insect-scale autonomous microrobots, with a particular emphasis on achieving fast, lifelike locomotion through compact, integrated control systems. Iwata’s major contributions include the development of a pulse-type hardware neural network integrated circuit (IC) that serves as a driving waveform generator for MEMS microrobots, enabling them to walk without external computation. In his most cited work (2016, 14 citations), he demonstrated a SMA actuator and neural network IC system for a hexapod microrobot, achieving walking motion in a device small enough to be fabricated from silicon wafers. His subsequent studies (2016, 13 citations; 2014, 10 citations) refined this approach, mounting bare-chip neural ICs directly onto the microrobot body. By replacing bulky microcontrollers with dedicated analog neural circuits, Iwata has advanced the goal of truly autonomous, insect-like robots—a critical step for applications in search-and-rescue, environmental monitoring, and micro-manipulation. His work stands out for its elegant fusion of MEMS fabrication and neuromorphic engineering.
