23.3: Tactile Sensor Based on Piezoelectric Resonance
We discuss here about the realization of tactile sensor based on the principle of change in piezoelectric resonance frequency with the applied pressure. An array of electrodes has been adopted on either side of the PZT material to have independent resonators. The common areas sandwiched between the electrodes and excitable at resonance frequency of the PZT material are used to form the sensitiv...
متن کاملDesign and Construction of a Novel Tactile Sensor for Measuring Contact-Force, Based on Piezoelectric Effect
In this paper, design and construction of a tactile sensor for measuring contact-force is presented. Mechanism of measuring contact-force in this tactile sensor is based on impedance changing of piezoelectric crystal and voltage of different points in circuit as a result of applying force on the crystal. By considering a specific point in the circuit and recording the changes of its voltage, ma...
متن کاملPsychological tactile sensor structure based on piezoelectric nanowire cell arrays
To produce artificial psychological feeling, especially ‘pain’, an electrical structure that mimics human skin has been studied. Touch by a sharp and a blunt object induces different deformations of the skin of human fingers. In order to imitate this phenomenon, a skin-mimicking device employing piezoelectric nanowire sensor arrays is used to generate an electrical ‘pain’ signal with signal pro...

متن کاملAn Endoscopic Grasper Tool with a Supported Piezoelectric Tactile Sensor
In this study, we describe the design of a tactile sensor based on polyvinylidene fluoride (PVDF). The sensor exhibits high force sensitivity and linearity. This sensor is integrated with an endoscopic grasper tool and can be used in minimally invasive surgeries. It consists of three distinct layers. A rigid micro-machined tooth-like silicon constitutes the top layer of the grasper, and the Ple...
