A KAUST-led team developed a superabsorbent polyacrylate film for passive cooling, combining radiative and evaporative techniques without extra energy. The film uses sodium polyacrylate to absorb moisture and form a reflective film, reducing solar heating. Experiments showed the film lowered temperatures by five degrees Celsius, with simulations indicating a 3.3 percent reduction in total energy consumption. Why it matters: This innovation offers a sustainable alternative to traditional cooling systems, reducing carbon emissions and strain on energy grids in hot climates.
KAUST hosted the Falling Walls Lab, featuring 22 finalists presenting their product or venture ideas. The winner, Aftab Hussain, presented a reusable, flexible, and smartphone-controlled smart thermal patch for chronic pain, intended as an alternative to existing solutions. The event served as a qualifier for the international Falling Walls Lab Finale in Berlin. Why it matters: Showcases KAUST's focus on innovation and provides a platform for students to develop solutions addressing global challenges, fostering entrepreneurship in the region.
KAUST researchers created a flexible temperature array by drawing a resistor structure with a silver conductive ink pen on Post-it paper. The array functions as an artificial skin sensor. The device demonstrates a low-cost approach to wearable sensors. Why it matters: This research offers a path to scalable and accessible sensor technology for health monitoring and other applications in the region.
KAUST researchers have developed a passive cooling device that uses gravity and radiative cooling to extract water from the atmosphere without electricity. The device reflects thermal energy back to the sky while collecting water using gravity and a lubricant coating to eliminate water droplet pinning. Tested in Thuwal, Saudi Arabia, the system nearly doubled the water collection rate compared to other atmospheric water harvesting technologies. Why it matters: This innovation could improve the efficiency and adoption of solar cells in arid regions by providing a sustainable, electricity-free cooling and water harvesting solution.
KAUST researchers have developed solar panels with 4D-printed legs that readjust their position to track the sun's movement without consuming electrical energy. The design uses smart materials that contract when exposed to sunlight, tilting the panel towards the sun. A multidisciplinary team of interns collaborated on the project, integrating physics, electrical engineering, and mechanical engineering expertise. Why it matters: This low-cost, energy-efficient solar-tracking technology could significantly increase the energy output of solar cells, offering a viable renewable energy solution for the region and beyond.
KAUST is spearheading geothermal energy research in Saudi Arabia to support the Kingdom's Vision 2030 goals. In early 2024, KAUST and TAQA Geothermal partnered to drill a 400-meter test well on the KAUST campus for subsurface data collection. KAUST aims to serve as a testbed for geothermal technology development and deployment across the country. Why it matters: Geothermal energy offers a consistent, weather-independent renewable energy source that could significantly reduce emissions and boost economic efficiency in Saudi Arabia.
KAUST Ph.D. candidate Ahmed Alfadhel won the IEEE best research paper award for his work on artificial skin. The artificial skin design uses a flexible magnetic nano-composite cilia surface with a magnetic field sensing element. The device exhibits unprecedented flexibility due to the embedding of magnetic cilia and the sensing element in a polymeric surface. Why it matters: This research enables the development of cheaper, more versatile tactile sensors for health monitoring, robotics, and prosthetics, potentially advancing personalized healthcare and human-machine interfaces in the region.
