Both laboratories' reference standards are electrically calibrated pyroelectric
radiometers (ECPRs) that have been previously calibrated against the primary standards.
Heat can be converted to electricity using something called the pyroelectric
effect, first described by the Greek philosopher Theophrastus in 314 B.
Inexpensive passive-infrared (PIR) motion sensors, or pyroelectric
sensors, like those commonly used for home lighting control, exploit both these features.
Energy harvesting with piezoelectric and pyroelectric
Several kinds of sensors currently can provide information on occupancy, such as video cameras equipped with people-counting software, optical tripwires and pyroelectric
infrared (PIR) motion sensors that count the number of people crossing a particular area, and sensors that measure the concentration of [CO.
and thermal strain effect of piezoelectric (PVDF and PZT) devices.
The book is presented in 11 chapters which cover topics such as scaling effects in organic transistors and transistor-based chemical sensors, organic thin-film transistors for inorganic substance monitoring, strain and pressure sensors based on organic field-effect transistors, Integrated pyroelectric
sensors, organic chemical and biological sensors based on light-emitting diodes, organic semiconductor lasers as integrated light sources for optical sensors, and electrophoretically deposited polymers for organic electronics.
It is a semi-crystalline polymer with --CH2-CF2-as repeating unit and exhibits unique piezoelectric, pyroelectric
, ferroelectric, and nonlinear optical properties, which promote their use in many technological applications including sensors (biomedical cardiopulmonary sensors, ultrasonic transducer, radiation detector)  actuators (hydrophone, microphone, headphone, generator) , nonlinear optical component and fiber optics and ferroelectric memory .
We observed spontaneous motor activities and spatial memory task of mice using pyroelectric
infrared sensor and programmed video tracking system, respectively.
In FTIR, a thermal detector is based on pyroelectric
materials or on solid-state semiconductor devices using photovoltaic or photoconductive principles.
The Rensselaer device uses pyroelectric
crystals that produce a strong electric field when heated or cooled to initiate the fusion reaction.
He used a pyroelectric
infrared detector made of a crystal of triglycinesulfate.
