Abstract Precious metals are core assets for the development of modern technologies in various fields. Their scarcity poses question their cost, life cycle and reuse. Recently, an emerging catalysis employing contact-electrification (CE) at water-solid interfaces to drive redox reaction, called contact-electro-catalysis (CEC), has been used develop metal free mechano-catalytic methods efficiently degrade refractory organic compounds, produce hydrogen peroxide, or leach from spent Li-Ion...
The magnetic flux gate sensors based on Faraday's Law of Induction are widely used for DC or extremely low frequency field detection. Recently, as the fast development multiferroics and magnetoelectric (ME) composite materials, a new technology ME coupling effect is emerging potential devices application. Here, we report sensor (MEFGS) weak detection first time, which works similar principle, but effect. proposed MEFGS has shuttle-shaped configuration made amorphous FeBSi alloy (Metglas)...
With the development of wearable devices and Internet Things (IoT), there is a growing demand for portable comfortable human health monitoring devices. Because advantages biocompatibility, relatively large piezoelectric coefficients, nonpyroelectricity, poly(L-lactic acid) (PLLA) polymers have been greatly utilized in applications tissue engineering, sensors, energy harvesting In this investigation, PLLA film was fabricated first time real-time stethoscope pulse wave sensor applications....
Abstract Although various magnetic sensors have been developed, tiny object detection is still a challenging issue in some cases, such as capsule position detection, endoscope navigation, and the of devices hidden in/on human body.

Conventionally, to produce a linear motion, one motor's stator is employed drive runner moving forward or backward. So far, there almost no report of electromechanical motor piezoelectric ultrasonic that can directly generate two symmetrical motions, while this function desired for precise scissoring and grasping in the minimally invasive surgery field. Herein, we brand-new symmetric-actuating piezoceramic capable generating motions outputs without additional mechanical transmission...
It is an important scientific and engineering challenge to sense a weak magnetic field HAC at extremely low-frequency (LF) below 1 Hz due the large LF noise. In this work, we presented amplitude modulation method (AMM) for quasi-static detection based on magnetoelectric (ME) sensor lock-in amplifier. Different from previously reported frequency conversion technology, signal demodulated directly output response of ME driven its resonance frequency. Experimental results demonstrated that...

Abstract Low‐temperature cofired ceramic technology is the prerequisite for producing advanced integrated piezoelectric devices that enable modern micro‐electromechanical systems because of merits such as high level compactness and ultralow drive voltage. However, piezoceramic structure with shear‐type outputs, a most fundamental functional electronic element, has never been successfully fabricated into multilayer form by method decades. Technical manufacture requirements parallel applied...
This study reports the improvement in magnetoelectric (ME) coupling effect a locally heat-treated FeBSi (Metglas)/Pb(Mg1/3Nb2/3)O3-PbZrO3-PbTiO3 single crystal laminated composite under zero magnetic bias. The high-temperature pulse laser treatment could induce local crystallization along scanning line, but adjacent domains remained still amorphous, which resulted thermal and lattice mismatch. Therefore, it produce residual stress between crystalline amorphous phases, generated an internal...
Magnetoelectric (ME) sensors are widely studied and well suited for current condition monitoring in smart grids due to their high sensitivity, low power consumption, compact size. However, designing ME that simultaneously achieve magnetic noise a large linear range remains challenging. In this work, we propose systematically study multilayered magnetoelectric sensor (MLMS). We experimentally demonstrate the voltage is effectively suppressed by connecting piezoelectric elements of MLMS...
