This session invites presentations on a wide range of topics, from basic research to applied research, related to mechatronics with representative dimensions in the micro/nano meter range. Mechatronic systems consist of mechanisms, actuators, sensors, controllers, and energy sources, which organically integrate to function as intelligent machines. These systems are advancing in various fields such as energy, information, bio-medical, MEMS, and IoT systems. The session will broadly discuss the latest research on engineering approaches, from understanding and analyzing fundamental processes in micro areas to designing and evaluating system functions.
