| Research Abstract |
Handwriting-electric signal transformation technique utilizing piezoelectric porous sheets has been studied. Direct conversion of the brush pressure to an electric signal by the piezoelectricity was effective compared with other considerable methods. Both piezoelectric and elastic properties of the sheet were precisely studied by means of dielectric and nonlinear permittivity measurements. It was found that the sheet is very soft in thickness and an oscillating damping characteristic is also remarkable. A touch and release sensor based on this technique was also tested.
