Title:
Equipment for temperature detection and related methods
Document Type and Number:
Japanese Patent JP6329269
Kind Code:
B2
Abstract:
An apparatus 100 comprises a substrate 102 ; a sensing material 104 for example comprising one or more of a carbon foam, aluminium foam or a graphene foam, located on the substrate; a first pair of contacts 106 coupled to the sensing material and separated by a first distance 108; and a second pair of contacts 110 coupled to the sensing material and separated by a second distance 112, the second distance being greater than the first distance. The apparatus is configured to provide a first electrical property measurement, such as resistance, resistivity, current, current density, or voltage, between the first pair of contacts and to provide a second electrical property measurement between the second pair of contacts. The first and second electrical property measurements are used in determining an ambient temperature and/or a substrate temperature. Also disclosed is a controller for use with such an apparatus. The apparatus may be one or more of a mobile phone, a tablet computer, a laptop, a smart watch, personal digital assistant, or a digital camera, for example.
