A wirelessly powered ingestible electronic capsule with programmable soft phase-change actuation delivers a peak force of 3.8 newtons and ~250 cubic millimeters stroke in confined geometry.
- Why it matters: Pill-sized ingestible capsules struggle to combine controllable high mechanical output with sufficient onboard power for effective in vivo GI therapeutic actions.
- What they did: The capsule uses bidirectional thermoelectric regulation and rigid-soft coupling, powered by wireless transfer achieving 9.15 watts per cubic centimeter at a 5-centimeter distance.
- The result: In beagles, the system enables feasible mechanical interventions and supports modular end-effectors for tissue acquisition, site-directed liquid/gel delivery, and active biofluid sampling under magnetic navigation.
