Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Implantable defibrillator with left ventricular assist device compatibility [PDF]

Interactive CardioVascular and Thoracic Surgery, 2009
Implanted defibrillator (ICD) and HeartMate-II (Thoratec, Pleasanton, CA, USA) left ventricular assist device (LVAD) incompatibilities have been reported. In order to show which ICD would function regularly in Heart Mate II recipients, we conducted a systematic review of 39 consecutive patients with implanted ICD and HeartMate-II from our institution's

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

Advanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.
