Voltage responsivity is a main target to enhance the performance of pyroelectric sensors. A partially covered, top electr

In the experimental results, the proposed electrode layout with an array type in ZnO pyroelectric sensors possessed higher voltage signals, about 3.6 times that of a fully covered type, and about 2 times th

Moreover, a finite element model is used to explore the temperature variation rate in ZnO pyroelectric sensors for both the fully covered and the partially covered electrodes. In the simulation results, the partially covered electrode can indeed improve the temperatur

Introduction Multilayer pyroelectric sensors have been successfully used in many applications, such as pollution monitoring, hot image detectors, intruder alarms, and gas analysis. They possess many advantages including no

The conventional pyroelectric sensors are comprised of a pyroelectriclayer sandwiched between top and
6、bottom electrodes. The topside is exposed to a heat source. The dynamic response currentof pyroelectric sensors is proportional to the temperaturevariation rate of pyroelectric layers 1. A higher temperaturevariation rate in the pyroelectric layer leads to a higher response current for the pyroelect

A partially covered,top electrode has been proven to result in a higher responsivity than that of a fully covered electrode because it opens windows for the ZnO layer to directly come into contact with theheat source 4. Therefore, the electrode layout plays an important role in pyroelec

ZnO is a unique material because it possesses various prop-erties like semiconductivity, piezoelectricity, and pyroelectricity.

The most densely packed and thermodynamically favorable growth orientation in a ZnO wurtzite structure is the one with the c-axis perpendicular to a substrate. ZnO films, with the c-axis normal to

The pyroelectricity of ZnO is attributable to non-centro-symmetrical crystals and has a specific polar axis along the direction of spontaneous polarization 1, 2. Given that Z
