Title:
HEAT SENSOR
Document Type and Number:
WIPO Patent Application WO/2013/011753
Kind Code:
A1
Abstract:
A heat sensor (1) is provided with a sensor section (10), a heat dissipating section (for instance, a movable member), a signal fetching section (for instance, a movable member), and a supporting substrate (21) that supports the signal fetching section. The sensor section (10) has a pyroelectric material layer (13), and an electrode section (18), which outputs electrical signals corresponding to changes of spontaneous polarization of the pyroelectric material layer (13) due to temperature changes due to infrared irradiation. The heat dissipating section dissipates heat by periodically propagating heat accumulated in the sensor section (10) to the outside. The signal fetching section periodically fetches the electrical signals from the electrode section (18) of the sensor section (10). The signal fetching section is not in contact with the electrode section (18) of the sensor section (10) when the heat dissipating section is not dissipating heat.
