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,

Dirac‐Source Linear X‐Ray Detection Diode

Advanced Functional Materials, EarlyView.
Monolayer graphene imparts near linear current‐voltage behavior to a perovskite X‐ray detection diode, contrasting with conventional diode‐like responses. Exploiting graphene's Dirac dispersion and a Schottky‐like back‐to‐back junction, the device achieves six‐orders‐of‐magnitude dark current suppression while retaining linearity over 200 V, enabling ...

The form of etch rate minima in wet chemical anisotropic etching of silicon [PDF]

Journal of Micromechanics and Microengineering, 1996
Etching of monocrystalline silicon in alkaline based solutions leads to a deep minimum in the etch rate crystallographically oriented along [Left angle bracket]111[Right Angle Bracket]. The details of the form of the minimum (angular dependence of the etch rate) are investigated and discussed in a framework of steps originating from spontaneous ...
