摘要

采用三个共线超声换能器设计了一种手写输入系统。这些共线聚偏氟乙烯(PVDF)换能器是专门为手写输入系统设计的，可以在任何方向上提供大的可写区域。为手写系统开发了驱动电路和检测电路。这种基于二维位置跟踪的手写输入系统具有可写面积大(A4纸)、驱动电压低(5 V)、不依赖于手写板或笔的特点。

Handwriting Input System Based on Ultrasonic Transducers

A handwriting input system was developed using three collinear ultrasonic transducers. These collinear polyvinylidene fluoride (PVDF) transducers were specially designed for the handwriting input system to give a large writeable area with writing in any direction. Driver and detection circuits were developed for the handwriting system. This handwriting input system based on 2-dimensional position tracing has large writeable area (A4 paper), low drive voltage (5 V), and is independent of the handwriting pad or the pen.
