Abstract

Sensing vibration is a basic feature of human interaction with the environment, providing essential information about texture and touching object. Pacinian corpuscle, one of tactile mechanoreceptors plays important role of detecting the vibration stimulus to the skin. Here, we report artificial Pacinian sensor (APS) that consists of piezoelectric polyvinylidene fluoride (PVDF) film and soft polymer structure that present fast adaptation characteristics and a high natural frequency. For tuning the natural frequency of the device, we designed the beam structure, with a soft fixed end and a forced weight at the midpoint. The APS showcased natural frequency around 200 Hz and high sensitivity 26.71 mV/N. After attaching the sensor on the fingertip, we tested gripping of the object, demonstrating the similar result with biological experiment. Using the APS, we showed various vibration experiments such as the grating scribing, dropping the ball and identifying several textures along with artificial intelligence. It is demonstrated that our tactile sensor has a potential in wearable devices, robotic hands, augmented/virtual reality and prosthetics.

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
