Wang, Junxian (author), Santhosh, Sabin (author), Colomés, Oriol (author), Capaldo, Matteo (author), Yang, Liang (author)The hydrofoil harnesses wave energy and converts it into thrust. In this paper, we present the results of the first experimental study investigating the dynamic behavior of a fully passive foil with spring-loaded pitch and heave in regular waves. Our study shows that the real-time load signal is multi-harmonic with strong superposition,...journal article 2023

Xu, Weitao (author), Xue, Wanli (author), Lin, Qi (author), Lan, G. (author), Feng, Xingyu (author), Wei, Bo (author), Luo, Chengwen (author), Li, Wei (author), Zomaya, Albert Y. (author)Smart space has emerged as a new paradigm that combines sensing, communication, and artificial intelligence technologies to offer various customized services. A fundamental requirement of these services is person identification. Although a variety of person-identification approaches has been proposed, they suffer from several limitations in...journal article 2022

Sharma, Suryansh (author), Simha, A. (author), Venkatesha Prasad, Ranga Rao (author), Gokhale, V. (author), Narayana, S. (author)In this letter, we present Hermes - a novel, low-cost, wireless, batteryless, energy harvesting system for aerial vehicles for sensing wind speed and Angle of Attack (AoA) concurrently. Hermes comprises a set of piezoelectric films which flutter due to incoming wind and the characteristics of this aeroelastic flutter are utilized for...journal article 2021

Deutz, D.B. (author), Mascarenhas, N.T. (author), van der Zwaag, S. (author), Groen, W.A. (author)In this study, the influence of Li substitution on the piezoelectric performance of lead-free K<sub>0.5</sub>Na<sub>0.5</sub>NbO<sub>3</sub> (KNN)-epoxy composites is explored. KNN piezoceramic particles modified with 0-12 mol% of Li are prepared via a double calcination technique, resulting in a perovskite particulate which transitions from...journal article 2016

Van den Ende, D.A. (author)The piezoelectric effect, which causes a material to generate a voltage when it deforms, is very suitable for making integrated sensors, and (micro-) generators. However, conventional piezoelectric materials are either brittle ceramics or certain polymers with a low thermal stability, which limits their practical application to certain specific...doctoral thesis 2012
