Tiny Machines That Rebuild Themselves on Demand
1+ week, 4+ day ago (209+ words) The system uses shape-memory alloys and magnetic latches to control folding. To lock and unlock folded configurations, the researchers integrated soft-magnetic pads with a low ferromagnetic transition temperature. These pads generate strong magnetic attraction to a nearby permanent magnet, stabilizing…...
A Soft Robot Only Uses Electric Current to Move
1+ week, 5+ day ago (478+ words) Princeton engineers built a motorless, durable soft robot using 3D printing and origami techniques. The robot combines a liquid crystal elastomer with embedded flexible electronic circuits. Targeted heating triggers the polymer hinges to bend and fold in pre-programmed ways. Princeton University,…...
