Piezoelectric vibration harvesters with strong electromechanical coupling coefficients have recently been combined nonlinear electrical techniques capable of tuning their resonant frequency as a solution to provide energy wireless sensor nodes from wideband vibrations. To be fully competitive, this approach requires piezoelectric generators global k2. However, the presence non-linear dielectric...

Timber harvesting guidelines formulated for north Queensland rainforests allowed economically viable harvests with minimal ecological impact. Harvesting procedures sought to minimize soil erosion, silting and turbidity in steams, destruction of trees in the residual stand, and disruption of natural habitats and processes. Forest officers selected the trees to be harvested, indicated the directi...

Plants can remove pollutants through direct absorption and by providing habitats for microbes to stimulate their activities. The aboveground plant biomass is usually harvested to remove pollutants absorbed in plant tissues. However, the effect of plant harvesting during summer on the performance of constructed wetlands and microbial abundance is unclear. In this study, three types of microcosms...

The plasmonic interaction between overlapping nanowires with and without structure singularities is studied analytically and numerically. A conformal transformation approach is adopted to predict analytically the optical response of overlapping nanowires in the quasi-static limit. Surface plasmon excitations are shown to exhibit a lower bound cutoff frequency, which blue-shifts when the overlap...

This paper presents the design of a novel low power electrostatic energy harvesting integrated circuit in AMI 0.7たm high voltage CMOS process. To increase the output power extracted from a variable capacitor acting as a mechanical to electrical energy converter, a novel controller unit is proposed to synchronize the operation of the energy harvesting circuit (EHC) with the motion of the capacit...

Interest in vibration energy harvesting technologies has increased significantly in the last decade, primarily due to the possibility of realizing ultra-low power sensor and communication circuits. In such low-power applications, it is paramount to maximize the efficiency of the harvesting system. Here, we propose the use of a simple MEMS cantilever as a power regulating hysteretic switch that ...
