Abstract: Use of micro machined silicon with thin films has led to the development of many micro/macro devices including membrane pressure sensors, micro valves and cantilevers. A brief review of the potential and future application of sensors and their likely impact in various industries is presented. A number of medical imaging applications employ transducer arrays operating in the frequency range 50-100 MHz, which corresponds to PZT film thickness in the range 20-40 microns. This paper deals with the design and characterization of a 50 MHz phased array transducer for skin and eye imaging with high degree of resolution using a new sol-gel technique. This offers new diagnostic possibilities in biomedical engineering. Peizo ceramic and their composites are the critical components for the most of the underwater acoustic devices. Frequencies less than 1 KHz are finding applications in long range communication in sea and ocean acoustic tomography. The design of such low frequency flexural transducer developed by the author has been described along with its acoustic performance. Use of smart sensors and actuators in aerospace and industries is likely to grow at a rapid pace. A short review of their application in automotive and aerospace ia also included in the end.
