Magneto-Acoustic System for Microrobot Steering

This technology utilizes an acoustic generator installed on an external base to create pressure differences from standing waves within a fluid medium, focusing multiple microrobots into a specific point to form a swarm. A magnetic field generator then creates a field to steer and move the swarm to a target location.

Using a single microrobot makes efficient drug delivery difficult due to limited storage capacity, and moving individual robots is time-consuming and costly.

This technology is a magneto-acoustic steering system and method that forms a microrobot swarm by applying sound waves to the fluid medium inside an object using multiple acoustic elements placed on a base, and then controls a magnetic field generator to stably guide the swarm to a target point. It can be applied to industrial robots and automated systems, improving drug delivery capacity and the steering of multiple microrobots.

Key Features:

• A magnetic field generator installed on the base that creates a magnetic field within the object.
• An acoustic generator installed on the base that transmits sound waves into the object.
• A magneto-acoustic system for microrobot steering that uses the pressure difference at the nodes of superimposed standing sound waves to focus multiple microrobots.
• Multiple microrobots injected into the object.
