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.

Climber, author, and wingsuit pilot Steph Davis spoke to the KAUST community on January 15 as part of the 2017 Winter Enrichment Program. The event was captured in photos by Lilit Hovhannisyan. The program was held at King Abdullah University of Science and Technology. Why it matters: Such enrichment programs can broaden the horizons of the KAUST community.
AIDRC researchers co-authored an accepted IEEE Vehicular Technology Magazine article on time reversal for 6G wireless communications. The article presents experimental results on the spatiotemporal focusing capability of time reversal across carrier frequencies. It examines requirements for efficient time reversal operation and synergies with technologies like reconfigurable intelligent surfaces. Why it matters: The research explores advancements in 6G wireless communication, with potential implications for coverage extension, sensing, and localization capabilities in the region.
A KAUST student blog post discusses optical wireless communications (OWC) as a solution to radio frequency exhaustion. OWC uses optical frequencies to carry electrical signals, offering advantages like high data rates and immunity to electromagnetic interference. Free-space optical (FSO) communication, a type of OWC, is applicable for inter-building connections and has seen use cases such as broadcasting during the 2010 FIFA World Cup. Why it matters: OWC research and deployment in the region can support high-bandwidth applications and provide cost-effective connectivity solutions, especially in challenging environments or disaster scenarios.
This paper presents the synthesis of a 1-DoF six-bar gripper mechanism for aerial grasping, designed for a task in the Mohamed Bin Zayed International Robotics Challenge (MBZIRC) 2020. The synthesis process involves selecting the mechanism class, determining the number of links and joints using algebraic methods, and optimizing link dimensions via geometric programming. The gripper was modeled in CAD software, additively manufactured, and mounted on a UAV with a DC motor for gripping spherical objects. Why it matters: The research contributes to advancements in robotics and aerial manipulation, with potential applications in various industries, particularly for tasks requiring remote object retrieval and manipulation.
