    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.

    Abstract translation: 装置100包括衬底102; 感测材料104，其例如包括位于衬底上的碳泡沫，泡沫铝或石墨烯泡沫中的一种或多种; 耦合到感测材料并分开第一距离108的第一对接触件106; 以及耦合到感测材料并分开第二距离112的第二对接触件110，第二距离大于第一距离。 该装置被配置成提供第一对触头之间的第一电性测量值，例如电阻，电阻率，电流，电流密度或电压，并提供第二对触头之间的第二电性测量值。 第一和第二电特性测量被用于确定环境温度和/或衬底温度。 还公开了用于这种设备的控制器。 例如，该设备可以是移动电话，平板电脑，膝上型电脑，智能手表，个人数字助理或数码相机中的一个或多个。
