Multifunctional Cantilevers as Working Elements in Solid-State Cooling Devices

چکیده

Despite the challenges of practical implementation, electrocaloric (EC) cooling remains a promising technology because its good scalability and high efficiency. Here, we investigate feasibility an EC device that couples electromechanical (EM) responses highly functionally, efficient, lead magnesium niobate ceramic material. We fabricated multifunctional cantilevers from this material characterized their electrical, EM properties. Two active were stacked in cascade structure, forming proof-of-concept device, which was then analyzed detail. The effect lower than itself, mainly due to poor solid-to-solid heat transfer. However, show use ethylene glycol thermal contact area can significantly reduce resistance, thereby improving Although solution is most likely impractical design point view, results clearly similar devices, non-destructive, surface-modification method, with same effectiveness as glycol, will have be developed resistance. hope study motivate further development devices.

Template Based Assembly for Solid State Cooling

This paper presents a fully dry assembly method to obtain densely packed arrays of parts from 400-800μm in size. This approach shows promise for enabling formation of a module of n and p type materials optimized for micro scale thermoelectric cooling performance. INTRODUCTION Inertial force (mass of the assembled parts) plays a critical role for part alignment and orienting in a dry microassemb...

Small Dielectric Spheres with High Refractive Index as New Multifunctional Elements for Optical Devices

The future of ultra-fast optical communication systems is inevitably connected with progress in optical circuits and nanoantennas. One of the key points of this progress is the creation of elementary components of optical devices with scattering diagrams tailored for redirecting the incident light in a desired manner. Here we demonstrate theoretically and experimentally that a small, simple, sp...
