NICOP - Self-Biased Dual Stimulation Energy Harvester for Wireless Structural Health Monitoring Sensor Nodes
Abstract
Self-Biased Dual Stimulation Energy Harvester for Wireless Structural Health Monitoring Sensor Nodes:a. Technical: This is a joint project between KIMS and Virginia Tech to be funded by ONRG and ONR HQ respectively. The research will focus on the synthesis of magnetoelectric composites through aerosol deposition (AD) and laser sintering of ceramics. This is collaboration is a perfect match of expertise: KIMS is the world leader in the AD process while Virginia Tech has been spearheading the research of energy harvesting technology. The objectives of the project are 1) to provide fundamental understanding of the laser sintering process for thick piezoelectric films grown on magnetostrictive substrates, 2) to develop high power density dual stimulation energy harvesting structure through systematic modeling and experimentation, in which Virginia Tech will develop analytical and finite element models that will be validated through experimentation at VT and KIMS using samples of different composition, dimension, configuration, and 3) to integrate the harvester with the structural health monitoring (SHM) nodes relevant to ONR with KIMS assisting in the integration of the harvester. Utilizing the optimized harvester structure, a self-biased laminate MME harvester using textured piezoelectric and magnetostrictive materials will be implemented to demonstrate a self-powered structural health monitoring node. At the end of program, the goal is to achieve a 1 cm^3 energy harvester that exhibits resonance in the vicinity of 100 Hz and power density above 25 mW/cm^3 (versus current state-of-the-art of 2 mW/cm^3). b. Relevance: The self-powered structural health monitoring technology will greatly accelerate the implementation of condition-based maintenance, which will enhance warfighting readiness and reduce operation cost. The research could have impact on the following Naval S&T Focus Areas: platform design & survivability, power projection & integrated defense, and Autonomy & Unmanned Systems. c. Coordination: Dr. Ignacio Perez of ONR 332 d. Desired Outcome: KIMS will achieve fundamental understanding of the laser sintering process for piezoelectric thick films grown on the magnetostrictive substrates and the materials integration in a complex self-powered architecture. The knowledge will accelerate the realization of condition-based monitoring and self-powered sensor network in autonomous systems with the greatly improved power density.
