Abstract

In this paper, the design of a heat exchanger system capable of removing heat from a patient in order to provoke a painful stimulus is presented. The system uses a thermoelectric cooler (Peltier device) as the main heat-transfer component. The main purpose is to extract heat from the subject, generating a cold sensation and hence generate an evoked potential by cold. The system is designed to be applied in biomedical systems. The experimental validation of the system is performed by applying the cold stimulus to the right hand of the patient, specifically in the T1 dermatome. Obtained results showed that the system is capable of provoking a pain sensation to the subject, as well as, detecting the corresponding temperature in a time suitable to be used with an EEG system, in order to find an EEG response pattern corresponding to the painful stimulus.
