Organic Electrochemical Transistors for Energy‐Autonomous Bioelectronics: Materials, Devices, and System Integration

Advanced Electronic Materials, EarlyView.
This review surveys organic electrochemical transistors as core building blocks for energy‐autonomous bio‐integrated electronics. We outline device physics, OMIEC materials, and electrolyte effects that enable sub‐volt, high‐gain operation, and discuss direct coupling with mechanical, thermal, and optical energy harvesters to realize battery‐free ...

Ionomer‐Free Iridium Anodes With Low Loading for Zero‐Gap Electrolyzers via Direct Atomic Layer Deposition

Advanced Energy Materials, EarlyView.
Iridium‐based anode catalyst layers for proton exchange membrane water electrolysis were fabricated via atomic layer deposition (ALD). Using custom‐made microporous substrates and thermal ALD, current densities of up to 2.5 A·cm−2${\rm A}\cdot{\rm cm}^{-2}$ at 0.21 mg·cm−2$\text{mg}\cdot {\text{cm}}^{-2}$ Ir loading were achieved.

Versatile Standing Wave Generation Between Arbitrarily Oriented Surfaces Using Acoustic Metasurface Deflectors and Retroreflectors

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A novel method for generating versatile standing wave fields using an acoustic metasurface deflector and retroreflector is introduced. By overcoming traditional constraints of parallel surfaces, the approach enables customizable wave patterns and enhances applications in particle manipulation.

Highly birefringent optical microfibers

Optics Express, 2010
Highly birefringent (Hi-Bi) air-clad silica microfibers (MFs) with wavelength and sub-wavelength scale transverse dimensions are studied theoretically and experimentally. Hi-Bi MFs are taper-drawn from the standard SMF-28 single mode fibers that are "pre-processed" by "cutting away" parts of the silica cladding on opposite sides of the fiber with a ...

Optimizing Electrode Design for Functional Activation of Human Pluripotent Stem Cell‐Derived Cardiomyocytes

Advanced NanoBiomed Research, EarlyView.
Electrical stimulation of human pluripotent stem cell‐derived cardiomyocytes is systematically investigated as a function of electrode material and configuration. Stimulation efficiency is found to be governed predominantly by electrode geometry, with increased electrode area and proximity to cells enabling more effective pacing.
