Unbalanced Torque Signal Generation for Kinetic Energy Harvesters

L. Kurmann [1],
[1] University of Freiburg, IMTEK, Freiburg, Germany

The problem of an unbalanced mechanical torque signal generation using nonpolar repulsion techniques is studied. To achieve such an unbalanced torque, several stator and rotor geometries, consisting of nonlinear permanent magnet spring batteries are investigated. It can be shown that an ... Mehr lesen

Simulation of a Multicomponent Trace Gas Electric Swing Adsorption

C. Geitner [1],
[1] Fraunhofer institute, Oberhausen, North Rhine-Westphalia, Germany

Introduction: Electric swing adsorption is a promising technique for energy efficient gas cleaning and adsorbate recovery. Contrary to state of the art temperature swing and pressure swing adsorption, one can control the mass flow independently of the heat flow for desorption in an ... Mehr lesen
