An Idea for Development of Intelligent Materials and Devices
智能材料与器件的发展设想

Based on the variation of spontaneous polarization Ps of ferroelectrics under applied electric field,temperature and stress,a concept of composite functional effect that different kinds of materials with different functional effects can be composed together to find a new material by multilayer and thin film integrated technologies was proposed to design new intelligent materials and devices. The principle demonstration and experimental results of a pyroelectric voltage transformer showed that this assumption is reasonable and feasible.
