Suspendable and Scalable Ultrasound‐Actuated ZnO‐Nanosheet‐Based Piezoelectric Microdevices for Wireless Electrical Stimulation of Cells

Small, EarlyView.
Silicon microtechnology enables the scalable fabrication of cytocompatible microdevices for wireless electrical stimulation. Microdevices smaller than a cell allow accurate interaction with single cells. By integrating piezoelectric nanostructures that can be actuated by ultrasound within the biomedical range, remote electrical cell stimulation is ...

Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia

Small, EarlyView.
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic

Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 105 s−1

Small, EarlyView.
A piezoelectric nanoindentation platform enables constant strain‐rate testing up to 105 s−1, extending experimental capabilities to extreme deformation regimes. Distinct hardness upturns are revealed across crystalline and amorphous materials, verified as intrinsic responses through quasi‐static reloading.

High‐Power Performance of Textured Piezoelectric Ceramics Through Synergistic A‐Site Donor and B‐Site Acceptor Doping

Small Methods, EarlyView.
A/B‐site co‐doping combined with templated grain growth enables synergistic defect and domain engineering in textured PIN–PMN–PT ceramics. The approach simultaneously enhances piezoelectric response and mechanical quality factor, achieving a balanced soft–hard characteristic.

Developing Implantable High‐Sensitivity Piezoelectric Thin‐Film Sensor to Monitor Partial Discharge of Generator Stator Windings

High Voltage, EarlyView.
ABSTRACT Insulation failures resulting from partial discharges (PD) in generator stator windings represent a leading cause of generator breakdowns. Conventional acoustic emission sensors for detecting PD ultrasonic signals are typically made from bulky piezoelectric materials and are restricted to external placement on the generator.

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

Artificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.
