Pyroelectric PZT sensors screen printed on glass

We present a pyroelectric device made from PZT screen printed on glass substrate. The pyroelectric thick film element is made of a stack of 50 μm PZT between silver electrodes. The device is placed under thermal load by a stream made of a sequence of hot and cold water flowing through a PDMS microchannel aligned of top of the device. With this, it is possible to apply fast temperature changes above of the pyroelectric device and then produced currents proportional to the temperature derivative.
