A novel piezoelectric inchworm actuator driven by one channel dc signal is developed in this article to simplify excitation of the actuators, and clamping force generated a motor two permanent magnets. The stack excited sensing signal, which separate photoelectric sensor detect position rotational mathematical model established predict motion slider. prototype proposed fabricated, mechanical output performance measured. At voltage 75 V frequency 3.2 Hz, average step 0.241 μm under no-load...
A low-frequency structure-control-type inertial actuator using miniaturized bimorph piezoelectric vibrators is proposed in this paper to achieve high resolution and stability with a large linear stroke. These are fabricated by bonding, thinning, patterning fabrication processes, which beneficial realize miniaturization increase output performance for the system. theoretical model based on work-energy analysis established predict displacement characteristics. An experimental system built...
Abstract Over the past half‐century, cardiac pacing technology has adhered to one basic system. However, many pacemaker‐related complications are related this system, particularly in terms of power supply and leads. Here, for first time a heart‐worn pacemaker strategy is presented, which allows batteryless powering leadless pacing. The feature attained via heart‐extrusion energy scavenging through micromachined piezoelectric thick film transducer. A record vivo output current 30 µA obtained...
In order to decrease the backward motion and improve efficiency, a walking type piezoelectric actuator has been proposed with two 'legs' based on parasitic of obliquely assembled PZT stacks. The structure principle are described, its experiment system is set up. Experimental results indicate could reduce effectively. minimum rate α= 2.26% achieved under condition phase difference θ= 180°, input voltage U= 120 V frequency f= 1 Hz; stepping displacement 0.24 μm 5 V, Hz 180°; maximum speed Vmax...
This paper proposes a wind-speed-adaptive resonant piezoelectric energy harvester for offshore wind collection (A-PEH). The device incorporates coil spring structure, which sets the maximum threshold of output rotational frequency, allowing A-PEH to maintain stable frequency over broader range speeds. When excitation falls within sub-resonant beam, becomes wind-speed-adaptive, enabling it operate in state wider Offshore winds exhibit an annual average speed exceeding 5.5 m/s with significant...
Abstract Precise and long-term electroanalysis at the single-cell level is crucial for accurate diagnosis monitoring of brain diseases. The reliable protection in areas outside signal acquisition points sharp ultramicroelectrode (UME) tips has a significant impact on sensitivity, fidelity, stability intracellular neural recording. However, it difficult existing UMEs to achieve controllable exposure tip functional structure, which affects their ability resist environmental interference shield...
Abstract To improve the overall performance of 3-DOF parallel position platforms such as resolution, travel range, and linearity, this study proposes a novel compact piezoelectric-electromagnetic platform (PEP). The supports motion in XYθZ directions operates three working types: high-speed mode (HSM), low-speed stepping (LSM), high-precision positioning (HPM). PEP utilizes signal control to switch modes, enabling tasks rapid movement, precise positioning, fine adjustments. It also object...
Abstract The ocean, as the Earth's largest yet underexploited energy reservoir, harbors immense potential for development. However, low‐frequency and low‐amplitude characteristics of oceanic waves pose significant limitations on harvesting efficiency electromagnetic generators. In contrast, advanced triboelectric nanogenerators exhibit distinct advantages in converting mechanical motion into electrical energy. This review systematically summarizes latest developments nanogenerator (TENG)...
Retrospective study OBJECTIVES: This aims to develop machine learning (ML) models combined with an explainable method for the prediction of surgical site infection (SSI) after posterior lumbar fusion surgery. In this retrospective, single-center study, a total 1016 consecutive patients who underwent surgery were included. A comprehensive dataset was established, encompassing demographic variables, comorbidities, preoperative evaluation, details related diagnosed disease, laboratory tests,...
