KAUST researchers are exploring thin-film device technologies using materials like printable organics and metal oxides for a greener Internet of Things (IoT). They propose wirelessly powered sensor nodes using energy harvesters to reduce reliance on batteries, which are costly and environmentally harmful. Large-area electronics, printed on flexible substrates, offer a more eco-friendly alternative to silicon-based technologies due to solution-based processing and lower production temperatures. Why it matters: This research contributes to a more sustainable and environmentally friendly IoT ecosystem, aligning with global efforts to reduce electronic waste and energy consumption.
A KAUST team led by Husam Alshareef has developed a microfabricated energy storage device with high energy and power density. The device uses nickel hydroxide as an active electrode material and achieves a volumetric capacitance density of 325 F/cm3. Fabricated using chemical bath deposition at room temperature, the device can power microelectronic devices. Why it matters: This research advances energy storage technology in the region, potentially impacting the development of microelectronics and portable power solutions.
Nate Hagens from the University of Minnesota spoke at KAUST's Winter Enrichment Program (WEP) 2018 about the intersection of energy, human behavior, and economics. Hagens argued that society functions as an energy-dissipating "superorganism," with human preferences correlated with increasing energy needs. He emphasized that energy, not money, is the real capital, but global society is running out of it. Why it matters: The talk highlights the importance of viewing society through an ecological lens, particularly in the context of the GCC region's reliance on energy resources.
KAUST's Functional Nanomaterials Laboratory (FuNL), led by Prof. Osman Bakr, focuses on synthesizing nanomaterials with novel optical, electronic, and magnetic properties for solar cells and other devices. The lab's research centers on controlling the size and composition of nanoparticles to optimize light absorption across different wavelengths. Unlike silicon-based solar cells, nanoparticle-based solar cells can be processed at low temperatures and potentially integrated with roll-to-roll printing. Why it matters: This research could lead to more efficient and versatile solar energy solutions, including printable photovoltaic thin films for buildings and flexible electronics.
The Directed Energy Research Center (DERC) in the UAE has partnered with the University of Pisa to develop electronically controlled surfaces for dynamic broadband radio-absorption. This collaboration aims to test new materials and manufacturing processes for flexible radio-absorbing surfaces suited for harsh environments like the UAE. The project seeks to create smart-shields, active electromagnetic frequency selective surfaces, and electromagnetic energy harvesting surfaces. Why it matters: The partnership accelerates innovation in applied electromagnetics and could lead to advancements in telecommunications, energy, and electromagnetic protection in the region.
KAUST faculty member Enrico Traversa is researching nanostructured materials for sustainable development in energy, environment, healthcare, and solid oxide fuel cells (SOFCs). His work focuses on developing next-generation SOFCs based on chemically stable proton-conducting electrolytes to reduce operating temperatures. Traversa also develops scaffold biomaterials for tissue regeneration, aiming to create heart tissue using patient-derived stem cells. Why it matters: This research contributes to KAUST's focus on energy, water, environment and food, with potential for advancements in clean energy and regenerative medicine.
KAUST Professor Derya Baran and her team at startup iyris have developed transparent solar panels that can turn windows into a source of renewable energy. The technology allows buildings to generate their own electricity, aligning with Saudi Vision 2030's goals for sustainable energy. iyris' first customer is the Red Sea Farm, another KAUST-based business, which aims to use the windows to improve plant growth and crop yield. Why it matters: This innovation could significantly reduce reliance on fossil fuels and promote sustainable urban development in the region, where cooling demands drive high electricity consumption.
