This technique ensures that the piezoelectric resonator
-- a quartz crystal of the highest quality -- will operate at a constant temperature.
Quartz crystal - the most common piezoelectric resonator
used in timing devices - is facing clear difficulties in overcoming the challenges of miniaturisation in the most advanced consumer devices.

Topics include: dielectricity, piezoelectricity, pyroelectricity, and ferroelectricity; a structural approach to thermodynamic study; ferroelectric-paraelectric phase transition thermodynamic modeling; formalism; electric characterization, piezoelectric resonators
and filters; high overtone bulk acoustic resonators; electrostrictive resonators, and thin film piezoelectric transducers.
Written for the professional engineer, this book focuses on the design of high-frequency oscillators with lumped, distributed, dielectric and piezoelectric resonators
An array of piezoelectric resonators
is used to identify chemical and biological agents.
The RAP instruments were fitted with a thermally stable sensor mounting block, which provided temperature control, and with microfluidic and electrical connections to the pair of piezoelectric resonators
in the sensor cassette.
Like other piezoelectric resonators
, the HBAR transducers exhibit l/f noise.
