Temperature sensor array system for thermal diagnostics on human disease

摘要

A technique using a plane temperature sensor array to dynamically image the transient temperature response of the human skin subject to intentionally applied heating or cooling was proposed. A human disease diagnostic system with satisfactory accuracy and rapid response speed was constructed. Preliminary experiments show the potential clinical application of this device, which is simple to fabricate and thus cheap in price. Further theoretical analysis shows that the surface heat flux may serve as a better thermal index for disease diagnostics than the commonly used surface temperature, due to that it included all the thermal contributions from any abnormal tissues underneath the skin. An approach was proposed to measure the skin surface heat flux using the currently constructed temperature sensor array system.
