A low-cost UWB sensor node powered by a piezoelectric harvester or solar cells

Nico de Rooij, Danick Briand, Anja Skrivervik, Pierre-André Farine, Franz-Josef Haug, Cyril Botteron, Pattanaphong Janphuang, Robert Andrew Lockhart, Christian Robert, Gabriele Tasselli

We propose an autonomous battery-less wireless sensor node that combines on a single printed circuit board an ultra-wideband (UWB) transmitter and its printed antenna, together with a piezoelectric cantilever and a solar cell array to harvest vibrations an ...

Harvesting Energy From a Rotating Gear Using an AFM-Like MEMS Piezoelectric Frequency Up-Converting Energy Harvester

Nico de Rooij, Danick Briand, Simon Nessim Henein, Pattanaphong Janphuang, Robert Andrew Lockhart, Don Isarakorn

This paper presents an analytical and experimental study of a compact configuration to harvest energy from a rotating gear using piezoelectric microelectromechanical system harvesters. The reported configuration realizes a contact-type frequency up-convers ...

Vibrational piezoelectric energy harvesters based on thinned bulk PZT sheets fabricated at the wafer level

Nico de Rooij, Danick Briand, Pattanaphong Janphuang, Robert Andrew Lockhart

We present a complete wafer level microfabrication process for the production of unimorph MEMS energy harvesters based on thinned bulk piezoelectric ceramic, lead zirconate titanate (PZT), sheets. This process eliminates the need for individual bonding of ...

Design optimization of vibration energy harvesters fabricated by lamination of thinned bulk-PZT on polymeric substrates

Nico de Rooij, Danick Briand, Andres Felipe Vasquez Quintero, Pattanaphong Janphuang, Robert Andrew Lockhart, Nadine Besse

The design optimization through modeling of a thinned bulk-PZT-based vibration energy harvester on a flexible polymeric substrate is presented. We also propose a simple foil-level fabrication process for their realization, by thinning the PZT down to 50 mu ...
