Abstract: This proposal combines the system integration and interdisciplinary R&D capabilities of the National Taiwan University NEMS/MEMS Team and the piezoelectric ceramics R&D as well as manufacturing technologies of Industrial Technology Research Insitute Materials Research Laboroatory (ITRI MRL) to develop piezoelectric ceramic based power supply modules. It is the intension of the research project to use the system integration persepctive as the paradigm to integrate mechanis, electronic and electrical engineering, manufacturing, and packaging, etc. to direct the design targets of materials research so as to develop a technology development platform that can circumvent the patent barriers set by other developed countries. Taking the systerm design perspctive to re-design the composition of peizoelectric ceramics, single-layer piezoelectric ceramic power supply modules will be used as the starting point to develop high-Q materials that can be sintered at low temperature in order to reduce manufacturing cost while improving system performnace such as power conversion efficienies, product sizes, etc. Multi-layer configuration will also be developed. Through the close collaborations, this proposal tries to achieve the goal of raising the system integration capabilities of our industries so as to make sure advanced technology product developed domestically can be marketed effectively around the globe. The execution as well as the planning of the research proposal will be constantly monitored by using the data collected and analyzed by the planning and market research staff of ITRI as well as collaborating industries.
As the power converstion efficiency of piezoelectric transformer is at least 7% higher than that of the coil-based electro-magnetic transformer with proper design and the energy density of piezoelectric transformer is very high, it is possible to further shrink the size and further improve the specification of power supply by using the piezoelectric transformer power supply technology pursued in this proposal. For example, piezoelectric transformer based power supply modules have gradually been used in many of the next-generation LCD TV due to the stringent heat dissipitation requirements. In addition, since LCD must be categorized as consumer electronics, its yield rate at the consumer side must be higher than 99.9%. This requirement is far more stringent than that of the LCD monitor specs. The traditional coil type transformer is known to have difficutly meeting this specification. In comparison, since the manufacturing process of piezoelectric transformer is similar to that of the passive components, it possesses the potential to significantly improve the yield rates to meet the LCD monitor specifications The alignment of market direction and technology development niche for using piezoelectric transformers in LCD TV will clearly provide a strong boot to the implementation of piezoelectric transformters. All these reasons make
