Communication

Communication

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Background:

Microswarms exhibit dynamic transformations and flexible assemblies in physiological environments, showing promise for medical applications.
Controlling artificial microswarms is challenging due to complex behaviors and influencing factors.

Purpose of the Study:

To develop a physically assisted artificial intelligence (AI) framework for predicting and controlling multimode swarm behaviors of magnetic microswarms.
To establish relationships between programmable magnetic field parameters and microswarm patterns for enhanced controllability.

Main Methods:

Employed a physically assisted AI framework to analyze and predict microswarm behaviors.
Modulated 12 parameters of a programmable magnetic field to generate diverse swarm patterns.
Developed a physical model to simulate magnetic fields and collective microswarm behaviors.
Utilized explainable AI for pattern classification and parameter-behavior relationship analysis.

Main Results:

Achieved 83.87% prediction accuracy for classifying various swarm patterns (liquid, rod, network, ribbon, flocculence, vortex).
Identified rod and vortex patterns as highly stable, suitable for precise manipulation.
Demonstrated environmentally adaptive swarm navigation and target hunting capabilities.

Conclusions:

The AI framework enables predictable control over magnetic microswarm behaviors.
This approach offers a viable strategy for micromanipulation and targeted delivery in clinical settings.
Advances the understanding of microswarm control for future biomedical applications.
