Piezoelectric Sensors and Sensor Materials
Journal of Electroceramics, 1998This paper reviews the current trends and historical development of piezoelectric sensors and sensor materials technology. It begins with a discussion of the bases of piezo- and ferroelectric activity, followed by an overview of the most commonly used piezoelectric ceramic: lead zirconate titanate (PZT).

Piezoelectric Cell Growth Sensor
Nature Biotechnology, 1991We have developed a reusable piezoelectric sensor that enables rapid characterization of cell viability and response to cell-affecting agents. This is accomplished via a novel polymer transduction principle that involves reaction of a pH-sensitive amphoteric polymer with metabolically generated acid. Subsequent adhesion of the protonated polymer to the

Piezoelectric Sorption Anesthetic Sensor
IEEE Transactions on Biomedical Engineering, 1981The piezoelectric sorption detection method is evaluated for use in construction of an inexpensive, rugged, compact, and fast sensor for measuring the concentration of inhalation anesthetics. 10 MHz quartz crystals were coated with various substances and their frequency shifts measured upon exposure to varying concentrations of halothane, enflurane ...

A broadly tuned self resonant knock sensor includes a piezoelectric element mounted on a central mounting stud. The element includes a generally annular vibratable portion having a variable radial dimension so as to exhibit resonant vibrations at a plurality of relatively closely spaced resonant frequencies essentially spanning an engine determined ...
