Objective: This proof of concept will exploit pyroelectric
harvesting in the emerging market of oscillating heat pipes (ohps) that can be used for cooling of electronics, Lighting, Solar panel and batteries.
Her research interests include pyroelectric
materials, infrared sensors, crystal growth, thin film and thick film technology, composite films and photovoltaic devices.
or passive infrared (PIR) sensors are very efficient for detecting various infrared emissions from a heat source, which allow them to be used for motion detection.
The composites, having PTC behavior, are mainly used as over current protectors, self-controlled heaters, and pyroelectric
sensors [6, 7]; whereas, the composites, exhibiting NTC behavior, are used as antistatic and EMI shielding materials , Yasin and his coworkers studied the electrical conduction behavior of epoxy/ carbon fiber composites (temperature range 25-275 K).
However, water continues to reveal unexpected properties, such as that ice nucleates at different rates on oppositely charged plates of a pyroelectric

InfraRed technology, each sensor can instantly switch a single light or a group of lights from off to on or from a dimmed state to on when motion is detected.
NPL has developed and patented a novel detection method employing pyroelectric
sensors, which convert ultrasonic energy into heat, generating electrical signals that are eventually used to form the ultrasound image.
The HSS node is designed to support multiple sensors such as a pyroelectric
infrared (PIR) motion sensor, a non-dispersive infrared (NDIR) C[O.
