In this paper we discuss dielectric elastomer actuators (DEA) as one of the most promising technologies in electroactive polymers (EAP). For tactile display applications a large number of actuator elements is essential. The multilayer technology presented here offers the possibility to build up independent actuators and arrays at a high density within one substrate. The functional principle of these...
This paper presents a small and lightweight tactile display system and describes its capabilities with respect to spatial and temporal tactile feedback. Each tactile display module is comprised of a 4times4 piezoelectric ultrasonic actuator array with a spatial resolution of 1.5 mm and a temporal resolution of 20 Hz. The objective of this research is to build a small and lightweight tactile display...
We present a tactile Respiratory Management System (tRMS) to manage and control breathing patterns of cancer patients undergoing radiation therapy. The system comprises of an array of small vibrating motors and a control box that supplies power to and provides a control interface for up to twelve motors through the parallel port of a standard personal computer. The vibrotactile array can be fastened...
The proposed demonstration stems from research on a low cost haptic virtual interaction platform for upper-limb rehabilitation. This work centers on the use of vibrotactile feedback in a virtual environment to help stroke patients perform simple repetitive motions and thereby overcome motor planning deficits. The device to be demonstrated consists of a sleeve with embedded optical markers and vibration...
In order to achieve awareness of collision during teleoperation and to support operator with valuable information (object stiffness and shape), we elaborated approaches to object parameter identification and delivering this information to the operator's skin through tactile display. The tactile sensory ability of the remote manipulator allows collision detection and exploration of contacting object...
This paper describes a new tactile device which produces stress fields in 3D space. Combined with mid-air and/or 3D stereoscopic displays, this device provides high-fidelity tactile feedback for interaction with visual objects. The principle is based on a nonlinear phenomenon of ultrasound; acoustic radiation pressure. The fabricated prototype device consists of 324 airborne ultrasound transducers,...
Tactile information plays a critical role in the human ability to manipulate objects with one's hands. Many environments require the use of protective gloves that diminish essential tactile feedback. Under these circumstances, seemingly simple tasks such as picking up an object can become very difficult. This paper introduces the SlipGlove, a novel device that uses an advanced sensing and actuation...
