摘要：
The stress-impedance (SI) effect is a new special physical effect which has the value of research and application in amorphous alloy found in recent years. The SI effect of an amorphous Fe(73.5)Cu(1)Nb(3)Si(13.5)B(9) alloy powder / silicone rubber piezomagnetic composite is investigated on theory and experiment. Optimal excitation method and various parameters are obtained, which provide a useful basis for the design of a signal source. Several key technologies, including the frequency of the oscillator, R(s) and design of time constant are discussed. Experimental results prove the work principle of exciting signal source is simple, realizable and the amorphous alloy can be used to produce force-sensitive elements in new type pressure sensors, which has wide application prospect and popularization value.
