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 ...

A wearable system of micromachined piezoelectric cantilevers coupled to a rotational oscillating mass for on-body energy harvesting

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

In this paper, we present a compact, wearable piezoelectric on-body harvesting system that uses a small eccentric mass from a common watch movement to mechanically deflect a set of micromachined piezoelectric cantilevers when excited by the low frequency m ...

An Automatic Test Bench for Complete Characterization of Vibration-Energy Harvesters

Nico de Rooij, Danick Briand, Jinyu Jason Ruan, Andres Felipe Vasquez Quintero, Pattanaphong Janphuang, Robert Andrew Lockhart

This paper presents an automated test bench, based on a rigorous measurement procedure, used to fully characterize vibration energy harvesters including determination of the resonance frequency, impedance, optimal load, and output power as a function of bo ...
