Title: MEMS based pyroelectric thermal energy harvester

Abstract

A pyroelectric thermal energy harvesting apparatus for generating an electric current includes a cantilevered layered pyroelectric capacitor extending between a first surface and a second surface, where the first surface includes a temperature difference from the second surface. The layered pyroelectric capacitor includes a conductive, bimetal top electrode layer, an intermediate pyroelectric dielectric layer and a conductive bottom electrode layer. In addition, a pair of proof masses is affixed at a distal end of the layered pyroelectric capacitor to face the first surface and the second surface, wherein the proof masses oscillate between the first surface and the second surface such that a pyroelectric current is generated in the pyroelectric capacitor due to temperature cycling when the proof masses alternately contact the first surface and the second surface.

Review of pyroelectric thermal energy harvesting and new MEMs based resonant energy conversion techniques

Conference Hunter, Scott Robert [ORNL]; Lavrik, Nickolay V [ORNL]; Mostafa, Salwa [ORNL]; ...

Harvesting electrical energy from thermal energy sources using pyroelectric conversion techniques has been under investigation for over 50 years, but it has not received the attention that thermoelectric energy harvesting techniques have during this time period. This lack of interest stems from early studies which found that the energy conversion efficiencies achievable using pyroelectric materials were several times less than those potentially achievable with thermoelectrics. More recent modeling and experimental studies have shown that pyroelectric techniques can be cost competitive with thermoelectrics and, using new temperature cycling techniques, has the potential to be several times as efficient as thermoelectrics undermore » « less
Harvesting mechanical and thermal energy by combining nanowires and phase change materials

Patent Radousky, Harry B.; Qian, Fang; Wang, Yinmin

A system is disclosed for harvesting at least one of mechanical or thermal energy. The system may have a flexible substrate, a plurality of electrically conductive nanowires secured to the substrate, and a plurality of electrically conductive metal layers. The metal layers may be disposed on the substrate and spaced apart from one another along a length of the substrate. The metal layers may be in electrically conductive contact with various ones of the nanowires. At least two of the metal layers may be attachable to an external device. At least one of movement or flexing of the substrate producesmore » « less

Development of MEMS based pyroelectric thermal energy harvesters

Conference Hunter, Scott Robert [ORNL]; Lavrik, Nickolay V [ORNL]; Bannuru, Thirumalesh [ORNL]; ...

The efficient conversion of waste thermal energy into electrical energy is of considerable interest due to the huge sources of low-grade thermal energy available in technologically advanced societies. Our group at the Oak Ridge National Laboratory (ORNL) is developing a new type of high efficiency thermal waste heat energy converter that can be used to actively cool electronic devices, concentrated photovoltaic solar cells, computers and large waste heat producing systems, while generating electricity that can be used to power remote monitoring sensor systems, or recycled to provide electrical power. The energy harvester is a temperature cycled pyroelectric thermal-to-electrical energy harvestermore » « less
Uncooled thin film pyroelectric IR detector with aerogel thermal isolation

Patent Ruffner, Judith A [Albuquerque, NM]; Bullington, Jeff A [Albuquerque, NM]; Clem, Paul G [Albuquerque, NM]; ...

A monolithic infrared detector structure which allows integration of pyroelectric thin films atop low thermal conductivity aerogel thin films. The structure comprises, from bottom to top, a substrate, an aerogel insulating layer, a lower electrode, a pyroelectric layer, and an upper electrode layer capped by a blacking layer. The aerogel can offer thermal conductivity less than that of air, while providing a much stronger monolithic alternative to cantilevered or suspended air-gap structures for pyroelectric thin film pixel arrays. Pb(Zr.sub.0.4 Ti.sub.0.6)O.sub.3 thin films deposited on these structures displayed viable pyroelectric properties, while processed at 550.degree. C.
