A Simple Finger Stimulator for Simultaneous Vibration and Heat Stimulation
In this study, we developed a simple finger stimulator that can simultaneously control vibration and heat stimulation. The newly developed stimulator consists of three parts, namely the control unit, drive unit, and an actuator. The control unit controls the stimulation type, frequency, intensity, and time. The drive unit amplifies the stimulation signal that drives the actuator. The actuator displays the vibration and heat stimuli quantitatively and simultaneously. Although the developed stimulator is simple, it has a wide frequency range of 0-400 Hz comprising 40 levels, and vibration stimulation intensity comprising 50 levels. The control temperature and stimulation temperature used for heat stimulation comprise four and eight levels, respectively. In addition, the developed stimulator has many advantages in terms of the overall system, stimulation control, and safety. Therefore, the developed stimulator can be used for integrative tactile perception and cognition studies on various vibration and heat sensations.
