Enhanced vibrational energy harvesting using non-linear stochastic resonance [PDF]

open access: yes, 2008
Stochastic resonance has seen wide application in the physical sciences as a tool to understand weak signal amplification by noise. However, this apparently counter- intuitive phenomenon does not appear to have been exploited as a tool to enhance ...

Power Switching Protocol for Two-way Relaying Network under Hardware Impairments [PDF]

open access: yes, 2015
In this paper, we analyze the impact of hardware impairments at relay node and source node (i.e. imperfect nodes) on network performance by evaluating outage probability based on the effective signal to noise and distortion ratio (SNDR).

Optimal Heartbeat Energy Harvesting using Electrostatic Energy Harvesters

open access: yesEnergy Technology, 2023
This paper presents the state space modeling and simulation of different micro electrostatic energy harvesters – in plane overlap, in plane gap closing and their compound structures – with freedom of movement in x, x-y and x-y-z axis. The structures are specially designed for energy harvesting of vibrations whose frequencies are lower than 100 Hz to be
