Pyroelectric thin film 12-element linear arrays (element size 0.4x0.9 mm(2)) have been fabricated by standard photolithography techniques on silicon substrates. A voltage responsivity of almost 800 V/W in air and 3000 V/W in vacuum is measured at low frequ ...
Sol-gel deposited Pb(Ti,Zr)O-3 thin films have been used to integrate pyroelectric arrays on silicon. The arrays of 1x12 (element size of 600 x 1100 mm(2)) and 1x50 elements (element size of 140 x 1100 mm(2)) are fabricated by standard photolithography tec ...
A phase diagram based on dielectric-permittivity-versus-temperature measurements and high-temperature X-ray diffractometry was proposed for 0.4Pb(Ni-1/3,Nb-1/3) O-3-xPbZrO(3)-(0.6-x)PbTiO3, (0.2 less than or equal to x less than or equal to 0.32) relaxor-f ...
The concept of photoinduced electron transfer has been explored for the development of polymeric transducers for optical ion-detection devices. For this purpose, a series of N-(9-anthrylmethyl)monoaza-18-crown-6 substituted poly(methacrylate)s were prepare ...
The fabrication and characterization of a microfabricated acoustic Lamb-wave device driven by a piezoelectric PZT (modified lead zirconate titanate Pb(Zr-x,Ti1-x)O-3) sol-gel thin film for use in mass-transport, mass-filtering and fluid-delivery systems ar ...
Performance of dielectric elastomer actuators is closely related to its breakdown field. On the other hand, to enhance the available energy, multilayer configuration is needed to increase the amount of active material. However, multilayer configuration suf ...
A spring comprising a plurality of elements, each element comprising a rigid portion and a flexible beam, the extremities of the flexible beam being supported by the rigid portion, the flexible beam having a single stable position, so that the flexible bea ...
