IBM has been granted a patent for its 4D-printed smart material technology for transporting microparticles. The material can be shaped-memory alloys or polymers that respond to external stimuli such as temperature, light, or electrical currents. Once deformed, the material returns to its original shape, allowing the researchers to induce movement and transport minute-sized particles that are difficult or impossible to transport using traditional methods. The technology uses machine learning algorithms to apply the proper stimulus to move the material, such as heat or light, to generate an action that results in an equal and opposite reaction. The system can monitor for deviations or blockages and resolve them, making it possible to deliver microparticles between 1-100 microns in diameter through various media. This technology has potential applications in medicine, such as delivering drugs to specific cells, and manufacturing, including miniature electronics and semiconductor manufacturing.
