Magnetic‐Driven Torque‐Induced Electrical Stimulation for Millisecond‐Scale Wireless Neuromodulation

open access: yesAdvanced Healthcare Materials, EarlyView.
MagTIES is a wireless neuromodulation technique with millisecond precision. It employs magnetic‐driven torque from magnetite nanodiscs to activate piezoelectric nanoparticles, enabling precise temporal control of neuronal activity and brain oscillations using weak, low‐frequency magnetic fields.

Interstitial N‐Strengthened Copper‐Based Bioactive Conductive Dressings Combined with Electromagnetic Fields for Enhanced Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
This study developed a nitrogen‐strengthened copper‐iron‐zinc (N‐CuFeZn) alloy bioactive dressing integrated with electromagnetic stimulation. The coaxial dressing, made from 0.04 mm filaments with 1120 MPa tensile strength, showed that electromagnetic activation enhanced therapeutic outcomes by increasing VEGF expression, promoting angiogenesis (2.1 ...

An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...
