KAUST and Saudi Aramco collaborated to develop a laser-based sensor for detecting trace amounts of gas leaks in petrochemical plants. The sensor uses machine learning to identify specific gases, differentiating it from previous sensors that only detect large leaks. The technology can differentiate between closely related industrial gases like benzene, toluene, ethyl benzene and xylene (BTEX). Why it matters: This innovation enables proactive monitoring and rapid pinpointing of leaks, enhancing safety, environmental protection, and operational efficiency in the petrochemical industry.
KAUST researchers developed a laser-based sensor that exploits the "chirp" phenomenon in semiconductor lasers to accurately measure gas temperature in combustion systems. The sensor uses spectroscopic measurements at very fast rates (1.0 MHz) and can measure temperature at the nanosecond timescale at repetition rates of thousands of kHz. The new sensor reduces uncertainty compared to previous methods and works rapidly in transient shock tube experiments. Why it matters: This in-house development provides a non-invasive, accurate, and easily implementable system for combustion research, with implications for understanding and improving energy efficiency.
KAUST held its third annual Sensor Initiative, hosting 70 delegates from KAUST and international institutions like MIT and UCLA. The interdisciplinary meeting focused on transforming sensor technologies and exploring applications. Researchers from KAUST and abroad presented on topics like chemical sensors and sustainable ecosystems. Why it matters: The initiative demonstrates KAUST's commitment to advancing sensor technology and fostering collaboration between local and international experts.
KAUST will host the "U.S. National Academy of Sciences – KAUST Frontiers of Sensor Science Symposium" in December, focusing on sensor technologies. The symposium, in collaboration with the U.S.-based National Academy of Sciences (NAS), will cover agriculture, biomedical applications, environment (smart cities), and materials science. Carlo Ratti, Director of MIT’s SENSEable City Lab, will deliver the keynote address. Why it matters: The event highlights KAUST's strategic focus on sensor technology and its role in fostering international collaboration in cutting-edge research areas relevant to regional development.
KAUST hosted the KAUST Sensor Initiative, convening experts in sensor development, material science, energy, communications, and data analysis. Live demonstrations showcased working prototypes, including a flexible sensor for monitoring the speed of dolphins developed by KAUST Ph.D. student Altynay Kaidarova. The initiative aims to advance a network of smarter, interactive physical IoT devices with embedded intelligent sensor technologies. Why it matters: This initiative highlights KAUST's role in fostering innovation in sensor technology and IoT, crucial for advancing smart infrastructure and environmental monitoring in the region.
KAUST Professor Boon Ooi, Nobel laureate Shuji Nakamura, and colleagues are collaborating on laser-based solid state lighting (SSL) and visible light communications (VLC). The team is using gallium nitride (GaN) to develop high-performance semiconductor laser devices, leveraging nanofabrication techniques at KAUST. They demonstrated that their laser-based VLC system is over 20 times faster than LED-based Li-Fi systems. Why it matters: This research could enable faster, more energy-efficient data transmission using visible light, with potential applications in both terrestrial and underwater communication.
The Directed Energy Research Center (DERC) is partnering with Montena Technology to study high-altitude electromagnetic pulses and design infrastructure safeguards. DERC is also collaborating with Radaz to evaluate ground penetrating and synthetic aperture radars in Abu Dhabi, aiming to identify natural resources. Additionally, DERC and Université de Picardie Jules Verne are working on laser sources and sensors, with a DERC researcher spending four years in France. Why it matters: These partnerships enhance DERC's research capabilities in critical areas like infrastructure protection, resource exploration, and advanced sensing technologies.
KAUST researchers are developing low-cost, mobile wireless sensors for smart city applications, focusing on flood monitoring. These sensors are designed to be deployed by UAVs and float in water, transmitting data to map flood extent. The system uses "Lagrangian sensing" to gather information from remote locations with minimal infrastructure. Why it matters: This technology offers a cost-effective solution for environmental monitoring and disaster management, particularly relevant for flood-prone areas in Saudi Arabia.
