Electrical energy generated by silicone elastomers filled with nanospring- carbon- nanotubes

Frank Nüesch

Dielectric elastomer generators (DEGs) are flexible capacitors that convert mechanical into electrical energy. They rely on an external voltage source to charge the capacitor during each operation cycle. An alternative to this is an autonomous DEG which op ...

Polarization Switching and Domain Wall Motion in Circular and Ring Capacitor Structures in PZT Thin Films

Nava Setter, Ludwig Feigl

Ferroelectric switching in circular and ring capacitors has been performed using a stroboscopic mode of piezoresponse force microscopy. A simple geometric model incorporating the characteristic domain wall motion is sufficient to describe the switching of ...

An improved trap design for decoupling multinuclear RF coils

Rolf Gruetter, Eulalia Serés Roig

Purpose Multinuclear magnetic resonance spectroscopy and imaging require a radiofrequency probe capable of transmitting and receiving at the proton and non-proton frequencies. To minimize coupling between probe elements tuned to different frequencies, LC ( ...

Development of low-temperature thick-film materials for piezoresistive sensors

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Caroline Jacq, Sonia Vionnet Menot

Thick-film materials are very advantageous for piezoresistive pressure and force sensors because of ease of processing, reliability and low cost. However, their applications are restricted because standard thick-film materials require processing temperatur ...

Design and Control of a Supercapacitor Storage System for Traction Applications

Alfred Rufer, Philippe Barrade

The storage system in this paper is made of supercapacitors. The main goal is to ensure an efficient energy management in a series hybrid vehicle, even if braking resistors are still needed. Design considerations are discussed. In particular the influence ...

Current capability and power density of supercapacitors: considerations on energy efficiency

Alfred Rufer, Philippe Barrade

Supercapacitors are components for energy storage. Due to their series resistors, the energy efficiency of supercapacitors can be low. In this paper, the unloading of supercapacitors with constant current and power are studied, to identify and take into ac ...

Considerations on the energy efficiency of a supercapacitive tank

Alfred Rufer, Philippe Barrade

Supercapacitors are electrochemical double layer capacitors, dedicated for the energ storage. Even if the energy density is still lower than that one of batteries, the supercapacitors are defined with a higher power density. The main advantage of that prop ...
