Abstract:

Research into solid state transducing techniques was directed toward the measurement of pressure, acceleration, temperature, and heat flow. Areas of investigation were unijunction transistors in oscillator circuits, piezocapacitive effects in high dielectric constant materials, mobilityAND DIFFUSION EFFECTS IN SEMICONDUCTORS, THE DIRECT AND INVERSE PIEZOELECTRIC EFFECTS, AND A UNIDIRECTIONAL TEMPERATURE INDEPENDENT STRAIN TRANSDUCER. Preliminary investigations were carried out on previously proposed heat flow rate schemes, piezoresistive shear effects, the acoustoelastic effect, piezoresistance in Ga Sb, the piezoresistive effect at high temperatures, high dielectric constant materials for temperature measurement together with experimental evaluations of piezoresistive and piezocapacitive ceramic materials. Experimental unijunction transistors temperature probes have been fabricated and evaluated, and experimentation has been initiated on the digital and analog measurement of heat transfer rate utilizing mobility and diffusions effects in semiconductors and digital accelerometers utilizing the inverse piezoelectric effect.
