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 led by Atif Shamim have developed a low-cost, 3D-printed wireless sensor node for real-time environmental monitoring. The disposable sensor nodes can detect noxious gases, temperature, and humidity, and have been tested in the lab and field, surviving drops and temperatures up to 70°C. The system aims to saturate high-risk areas with these sensors, linked wirelessly to fixed nodes that raise alarms. Why it matters: This innovation provides a cost-effective solution for large-scale environmental monitoring, addressing the limitations of expensive fixed sensors and satellite monitoring, and potentially revolutionizing early warning systems for wildfires and gas leaks in the region.
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 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 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 postdoctoral fellows Eloise Bihar and Abdellatif Ait Lahcen won Young Scientist awards at the Euroanalysis XX Conference in Turkey. Ait Lahcen won for his work on sensors detecting toxic compounds using ultrasound probes. Bihar won for her research on inkjet-printed biosensors for glucose detection, a collaboration between the Salama, Inal, and Baran groups at KAUST. Why it matters: The awards recognize KAUST's strength in developing innovative sensor technologies with potential applications in environmental monitoring and healthcare.
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.
KAUST alumnus Fahad Hossain (M.S. 2010, Ph.D. 2014) discusses his journey from KAUST to UC Berkeley, where he co-founded Serinus Labs Inc., a manufacturer of integrated silicon gas sensors. Serinus Labs develops gas-sensing solutions for air-quality monitoring, safety, and preventive healthcare. NASA became Serinus' first customer in 2018, contracting them to develop multi-gas sensors for the next generation of spacesuits. Why it matters: This highlights the impact of KAUST graduates in developing advanced sensor technologies and securing partnerships with leading organizations like NASA.
