A novel thermal tactile stimulator device for quantitative sensory testing.

This paper outlines the design and preliminary experimental results of a novel thermal stimulator device designed to measure, from some perspectives, brain health. The device delivers some thermal stimuli and asks the subject about his perception about them, thus checking the correctness of the perception and even the existence of certain perceptual illusions that would normally be present in healthy cortex and nervous system. This noninvasive sensory technology is cheap and easy to use, it has the potential to be used in telemonitoring systems and in empowering the individual to track his/her progression over time on the provided neuropathy tests.
