▎ 摘　　要

NOVELTY - The method involves comprising multiple electrical contacts (141) and a graphene sheet in a sensor (100) that electrically couples multiple electrical contacts. The electrical contacts are used to monitor a portion of the graphene sheets. The graphene sheets are positioned between the electrical contacts to determine a thermal property of a surface that is in contact with portion of the graphene sheet based on an effect of the thermal property on the portion of the graphene sheet. USE - Method for selective sensing. ADVANTAGE - The electrical contacts reduces cross-talk between the pairs of electrical contacts when a common power supply is used with multiple pairs of electrical contacts. The speed of the array of heating elements is increased relative to the surface, thus decreasing the speed of the array of heating elements relative to the surface and periodically changing the speed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for heating. DESCRIPTION OF DRAWING(S) - The drawing shows a side elevation view of a calorimetric sensor that includes a nanotube oriented between a pair of electrical contacts.
