Peppelman, Christian (author)Non-invasive head-worn sensors are an upcoming field of interest. Most commercial sensors and sensors presented in research papers are limited in their capabilities and require frequent user interaction. In this Thesis, we research the possibilities of overcoming some of these limitations and extending the capabilities of these sensors.master thesis 2023

PYTHAROULIOU, ANGELINA (author)The rapid increase in global population and rising demands have resulted in a shortage of clean water, depleting several of the Earth's reservoirs, especially those that reserve fresh water. Just 0.007% of the water on Earth is used to hydrate and feed billions of people, as determined by the water balance of the planet. Water-stressed nations...master thesis 2023

van den Oever, Sam (author)A growing energy demand has sparked interest into harvesting energy from the human body. Often, a rotational proof mass is used to harness energy for a wearable from kinetic motion of its user. The addition of a spring has the potential to significantly increase efficiency for these low-power rotational energy harvesters. In this research a...master thesis 2023

van den Bergh, Michael (author)Energy harvesters subtract energy from their surroundings and convert this to electrical energy. Even though energy output is generally low, energy harvesters can offer great value by offering the possibility of self-sustaining devices, combined with the developments in low power semiconductors. Many examples can be found of applications that...master thesis 2023

Yue, X. (author), Du, S. (author)In the past decades, inductor-based synchronized switch harvesting on inductor (SSHI) rectifiers have been widely employed in many active rectification systems for piezoelectric energy harvesting. Although SSHI rectifiers achieve high energy extraction performance compared to passive full-bridge rectifier (FBR), the performance greatly...journal article 2023

Wang, Junxian (author), Santhosh, Sabin (author), Colomes, 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

Ma, Dong (author), Lan, G. (author), Hu, Changshuo (author), Hassan, Mahbub (author), Hu, Wen (author), Mushfika, Upama (author), Uddin, Ashraf (author), Youssef, Moustafa (author)We design a system, SolarGest, which can recognize hand gestures near a solar-powered device by analyzing the patterns of the photocurrent. SolarGest is based on the observation that each gesture interferes with incident light rays on the solar panel in a unique way, leaving its discernible signature in harvested photocurrent. Using solar...journal article 2023
