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 ...

Understanding Neurodegenerative Diseases From the −Omics Perspective: Lessons Learnt
Annals of Neurology, EarlyView.As the population ages, certain neurodegenerative diseases (NDs) are becoming a major health issue. For this reason, this review will focus on the most common ND with onset after 65 years old; Alzheimer's disease, Parkinson's disease, Lewy body dementia, and frontotemporal dementia.

Force stimulation promotes nerve regeneration by restoring cellular energy
BMEMat, EarlyView.Mechanical stimulation can help nerves regenerate in various ways. We developed two devices (a piezo‐motor‐driven stretching device and a SAW‐based actuator) to apply mechanical stimulation to sciatic nerve and DRG neurons. Our study shows that appropriate mechanical force stimulation can promote regeneration by restoring the energy supply to the ...
