Design 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...

ZnO-based transparent thin-film transistors

Highly transparent ZnO-based thin-film transistors ~TFTs! are fabricated with optical transmission ~including substrate! of ;75% in the visible portion of the electromagnetic spectrum. Current– voltage measurements indicate n-channel, enhancement-mode TFT operation with excellent drain current saturation and a drain current on-to-off ratio of ;10. Threshold voltages and channel mobilities of de...

MEMS Pressure Sensor With Two Thin Film Piezoelectric Read-Out

We propose the structure to have only two pares of PZT thin films on the basis of [11]. This causes the structure to become simpler and easier to fabricate. And except its first vibration mode that is also the base mode, the other modes have no effect on the acceleration measurement. So it can be a better choice for the measurement of acceleration and it can have a huge potential as a micro-sen...
