We have already proposed a novel method to provide human tactile sensation using surface acoustic wave (SAW). A pulse modulated driving voltage excites temporal distribution of standing SAW. The distribution generates friction shift on the surface of a SAW substrate. When the surface with the burst SAW is explored, the friction shift can be perceived as(More)
We have already proposed a novel method to provide human tactile sensation using surface acoustic wave (SAW). In this paper, we propose "tele-touch", which realize reproduction of tactile sensation as if to rub remote solid surface. To generate tactile display control parameters, object surface is measured by a fabricated profile scanner. Control parameters(More)
Silicon field-effect transistors have now reached gate lengths of only a few tens of nanometers, containing a countable number of dopants in the channel. Such technological trend brought us to a research stage on devices working with one or a few dopant atoms. In this work, we review our most recent studies on key atom devices with fundamental structures of(More)
The impact of dopant atoms in transistor functionality has significantly changed over the past few decades. In downscaled transistors, discrete dopants with uncontrolled positions and number induce fluctuations in device operation. On the other hand, by gaining access to tunneling through individual dopants, a new type of devices is developed:(More)
This paper deals with proposal of a pen tablet interface combined with visual information. The interface employs surface acoustic wave (SAW) tactile display. Basic principle of the tactile display and its application for our proposal are described. Design and fabrication of an ultrasonic transducer are also reported. Development of the proposed interface(More)
