Intrinsically Linear and Robust Capacitive Strain Sensors Based on Area‐Variation Mechanism for Soft Machines

open access: yesAdvanced Intelligent Systems, EarlyView.
An intrinsically linear capacitive strain sensor based on an area‐variation mechanism is demonstrated. Lasermicromachined carbon fiber electrodes encapsulated in PDMS yield exceptional linearity and robustness. Integrated into smart gloves and soft continuum robot, this scalable strategy enables precise gesture recognition and real‐time shape ...

The Experimental Registration of the Evanescent Acoustic Wave in YX LiNbO3 Plate

open access: yesSensors, 2021
Evanescent acoustic waves are characterized by purely imaginary or complex wavenumbers. Earlier, in 2019 by using a three dimensional (3D) finite element method (FEM) the possibility of the excitation and registration of such waves in the piezoelectric ...

Interface Engineering in Piezoelectric‐on‐Insulator Platforms: Coupling of Electrons, Photons, and Phonons for Multifunctional Integration

open access: yesElectron, EarlyView.
The underlying interface physics and engineering strategies across key POI material systems, including LiNbO3/Si, LiNbO3/SiC, LiNbO3/diamond, and AlN/diamond, were reviewed. The key engineering strategies such as atomic‐scale bonding optimization, nanostructuring, ultrathin phonon‐bridge interlayers, and ferroelectric domain wall engineering for ...

Wide‐range and high‐resolution Young's modulus sensing enabled by a complementary indentation‐protrusion architecture

open access: yesFlexMat, EarlyView.
A tactile sensor integrating indentation and protrusion sensing within a single platform enables accurate perception of object Young's modulus. This complementary architecture expands the detectable Young's modulus range to 25.8–2639.2 kPa and achieves an object recognition accuracy of 94.27%, outperforming indentation‐only (84.59%) and protrusion‐only

Harmonic analysis of lossy piezoelectric composite transducers using the plane wave expansion method [PDF]

open access: yes, 2008
Periodic composite ultrasonic transducers oer many advantages but the periodic pillar architecture can give rise to unwanted modes of vibration which interfere with the piston like motion of the fundamental thickness mode.

Nonlocal Damage Mechanics for Quantification of Health for Piezoelectric Sensor

open access: yesApplied Sciences, 2018
In this paper, a novel method to quantify the incubation of damage on piezoelectric crystal is presented. An intrinsic length scale parameter obtained from nonlocal field theory is used as a novel measure for quantification of damage precursor.
