Description
Hengzhang Yang and nine co-authors built a microgripper whose fingers are two-layer strips that curl with heat, in this 2024 paper. The strips pair aluminum with silica glass, which expand at different rates, so a small voltage bends them. Left alone, the gripper rests closed because of stresses baked in during fabrication.
At five volts the fingers sweep through more than a hundred degrees in under ten milliseconds. The team picked up plastic microbeads and solder balls and set them onto a chip. A held bead survived shaking at thirty-five times gravity and impacts above sixteen hundred. The authors aim the device at micro-assembly and electronics packaging lines.
