Wirelessly Powered Soft Magnetic Robot with Microneedle for Electrical Stimulation and Drug Delivery

Advanced Intelligent Systems, EarlyView.
A wirelessly powered soft magnetic robot integrates microneedles to enable dual functions: electrical stimulation (86.7% efficiency at 6 cm, tunable 0–20 V voltage, 0.4–50 ms pulses) and drug delivery. It switches surfaces via magnetic fields for gastrointestinal tract locomotion and treatment, with in vitro validation in fresh pig gut showing ...
