Paper Abstract

The aim of this paper is to present a new micro-actuator, which is currently being used to design and develop high resolution, lightweight and compact interfaces for tactile information representation. Based on shape memory alloy (SMA) technology, the actuator is capable of producing a mechanic deformation on the skin of the user's fingertip in order to re-create a realistic touch sensation. This actuator of 1.5 mm diameter, 5 cm length, 150 mg weight, 0.7 mm total excursion, 170 mN pull force and 4 Hz bandwidth represents a high spatial and temporal resolution actuation principle for tactile feel displays. The SMA actuator's design concept, modeling and implementation are presented and described in detail. In conclusion, the prototype and preliminary performance results are reported and discussed.
