Smart Microrobot System Using Induced Electromotive Force

This technology is a wireless control system for an implantable helical microrobot that generates its own power to operate a light-emitting unit by acquiring induced electromotive force from an external magnetic field generator.

Conventional microrobots face limitations in performing therapeutic tasks and tracking their position within the human body due to the difficulty of providing a separate power supply for wireless operation.

This technology features a microrobot with a metallic head and a helical body that rotates and moves in response to an applied external magnetic field. During this process, it generates induced electromotive force from magnetic field changes to power a stacked LED (light-emitting unit). Applicable to industrial robots and automation systems, it improves the ability to position and perform therapeutic actions within the human body using induced electromotive force and wireless operation.

Key Features:

• A microrobot comprising a helical body portion that generates induced electromotive force from a magnetic field applied by a magnetic field generator.
• A magnetic field generator that surrounds the microrobot from outside the human body to generate a magnetic field, thereby inducing electromotive force in the microrobot.
• A light-emitting unit stacked on the body portion in a helical shape, which receives the induced electromotive force produced by the body portion to emit light.
• A power application unit that provides driving force to the microrobot.
