较系统、扼要地回顾了作者 2 0余年来在压电式传感器与测力仪、压电式执行器等方面的理论研究与产品开发情况 .其中对压电效应的理论研究成果 ,如切向灵敏度分布、石英晶体扭转效应、多种能量间的物性效应等 ,作了比较详细的介绍 .对所研发的压电式传感器与测力仪产品作了宏观介绍 .最后 ,对作者目前在上述领域所做的工作和对未来研究工作的想法作了简要阐述 .

Theoretical studies and products development of piezoelectric sensors, dynamometers and piezoelectric actuators in the first author′s research group over 20 years have been introduced briefly and systematically in this paper. It mainly focuses on the study of piezoelectric effects, such as the distribution of tangential sensitivity, the torsional effect of quartz crystals, and physical effects on the transition between various forms of energy. A brief prospect of our research work in the fields mentioned above is presented.
