A Piezoelectric Molecular Cocrystal with Unconventional π-Stacking

Crystal Growth & Design
We demonstrate the crystallization of a polar octafluoronaphthalene (OFN, \OFN)--phthalazine (Phth, \Phth) cocrystal, formed in a 1:2 ratio by slow evaporation. The crystal structure and vibrational properties of the cocrystal were determined using powder/single-crystal X-ray diffraction (XRD) and Fourier-Transform Infrared (FTIR) spectroscopy, and ...

Mechanoluminescent HOF Nanotransducers Enabled Sono‐Optogenetics in Parkinsonian Rats

Advanced Functional Materials, EarlyView.
We present a mechanoluminescent system utilizing porous hydrogen‐bonded organic frameworks (HOFs) as a toolkit for focused ultrasound‐triggered, non‐invasive light delivery to the deep brain in rats. This approach enables the specific activation of PV‐GPe neurons in dopamine‐depleted Parkinson's disease rat models, resulting in a comparable alleviation

50 GHz Piezoelectric Acoustic Filter

IEEE Journal of Microwaves
This paper presents significant frequency scaling of acoustic filter technology to 50 GHz. This achievement is enabled by the periodically poled piezoelectric film LiNbO3 multilayer stack, in which piezoelectric thin-films of alternating orientations are

Development of a Three‐Axis Planar Hall Magnetoresistance Sensor Using a Superparamagnetic Nanoparticle‐Based Flux Guide

Advanced Functional Materials, EarlyView.
A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.

Behavioral implications of piezoelectric stack actuators for control of micromanipulation [PDF]

Proceedings of IEEE International Conference on Robotics and Automation, 2002
A lumped-parameter model of a piezoelectric stack actuator has been developed to describe actuator behavior for purposes of control system analysis and design, and in particular for microrobotic applications requiring accurate position and/or force control. In addition to describing the input-output dynamic behavior, the proposed model explains aspects
