Displaying Tactile Sensation by SMA-Driven Vibration and Controlled Temperature for Cutaneous Sensation Assessment

Actuators
In this paper, we propose a novel tactile display that can present vibration patterns and thermal stimuli simultaneously. The vibration actuator employs a shape memory alloy (SMA) wire to generate micro-vibration with a frequency control of up to 300 Hz.
