Energy efficiency and harvest, speed and performance, flexibility and portability are key elements for innovation in the current consumer electronics markets. Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics ... Read More

FEM Modeling in Robust Design for Graphene-Based Electromagnetic Shielding

S. Elia [1], G. Granata [1], P. Lamberti [1], V. Tucci [1],
[1] University Of Salerno, Italy

Electromagnetic shielding design is usually approached referring to nominal values of the main parameters. This could lead to malfunctioning devices and its performance differ widely from what was really aimed at or, worse, the final design product could even be physically unrealizable. ... Read More

Creep Deformation Behavior of Heating Filaments in High Temperature Applications

B. Valentini [1],
[1] Plansee SE, Reutte, Austria

Resistive heating filaments used in high temperature applications at 2000°C and above are often made of refractory metals. The lifetime of such filaments is mainly limited by creep deformations which can in the worst case lead to a short circuit between filaments and other furnace ... Read More

Modeling of Piezoelectric Transducers Made of PZT for Energy Harvesting

J. Golebiowski [1], P. Bakolik [2],
[1] Lodz University of Technology, Department of Semiconductor and Optoelectronics Devices, Poland
[2] Lodz Univeristy of Technology, Poland

This work shows the results of modeling of piezoelectric transducers used to recover energy from mechanical vibrations. The analysis consists of usefulness of commercial ceramic PZT transducers to power electronic systems. Determined output load characteristics, characteristics of the ... Read More

Investigation of Ion Interactions and Space Charge Effects in a Time of Flight Ion Trap Resonator
