Energy harvesting technology is attracting huge attention and holds a promising future for generating electrical power. This process offers various environmentally friendly al‐ ternative energy sources. Especially, radio frequency (RF) energy has interesting key at‐ tributes that make it very attractive for low-power consumer electronics and wireless sensor networks (WSNs). Ambient RF energy co...

Photosynthetic organisms harvest sunlight with near unity quantum efficiency. The complexity of the electronic structure and energy transfer pathways within networks of photosynthetic pigment-protein complexes often obscures the mechanisms behind the efficient light-absorption-to-charge conversion process. Recent experiments, particularly using two-dimensional spectroscopy, have detected long-l...

The method to obtain electrical equivalent models of piezoelectric materials used in energy harvesting road traffic environment is presented in this paper. The experimental results are processed in order to determine the optimal topological structure and technology of the semiconductor elements used in the input stage of the power harvesting system. The non regulated power supply model under va...

In this work we examine the prospects for harvesting energy from flutter instabilities of a slender, flexible cylinder in an axial flow stream. We couple the fluid-solid model and include energy harvesting as curvature based damping. In the first instance we model the reduced order system comprising of an articulated rigid cylinder pair with discrete springs and dampers and demonstrate the scop...

All energy-harvesting schemes require some form of ‘‘intermediate’’ storage – batteries or capacitors that reservoir energy harvested from the environment. There are a number of reasons for this requirement. Ambien...

Wireless sensor networks (WSNs) play an increasingly important role in monitoring applications in many areas. With the emergence of the Internet-of-Things (IoT), many more lowpower sensors will need to be deployed in various environments to collect and monitor data about environmental factors in real time. Providing power supply to these sensor nodes becomes a critical challenge for realization...

Energy is a valuable resource in wireless communication, navigation and sensor nodes. Maintenance and replacement of batteries in battery-driven nodes may not be possible, cost-effective or suitable for many applications. On the other hand, energy harvesting provides sustainable and independent operation with very long life-time but usually with unregulated power flow. The design approaches in ...

We have performed time-resolved fluorescence measurements on photosystem II (PSII) containing membranes (BBY particles) from spinach with open reaction centers. The decay kinetics can be fitted with two main decay components with an average decay time of 150 ps. Comparison with recent kinetic exciton annihilation data on the major light-harvesting complex of PSII (LHCII) suggests that excitatio...
