A novel device for studying temperature and touch interactions.

ABSTRACT:

Background

Existing methods to study the effects of skin temperature on mechanical touch perception range from large hot plates, water baths, or bulky, water-controlled thermal contactors which have limited range and resolution. The limited capabilities of these methods prevent the study of thermo-tactile interactions at the finger level in a flexible and precisely controlled manner.

New method

Here, we combine small Proportional-Integral-Derivative (PID)-controlled Peltier elements with a calibrated shaker motor for a novel thermo-tactile stimulus delivery system capable of precisely controlling temperature and vibrotactile stimulation to the fingertip. This novel system enables parallel control of mechanical stimulation and thermal stimulation at congruent skin sites of th
