Sarah Wins second place at WEP poster competition

posted Jan 26, 2018, 4:09 PM by Khaled salama   [ updated Jan 26, 2018, 4:10 PM ]

In January 2018, King Abdullah University of Science and Technology (KAUST) hosted its seventh annual International Poster Competition for undergraduate students as part of the Winter Enrichment Program (WEP). This competition brings up to 50 students from around the globe together. Sarah Basyouni, an electrical engineering student at Effat University won the second place. Sarah spent last summer in our lab and developed wearable capacitive sensors for volatile organic compounds detected in particular ethanol. During her internship, she was an exemplary student. She put a lot of time and effort to make sure her design worked. She worked with Dr Karumbaiah Nanaiah, a postdoctoral fellow in our group mentored her during the summer. We are looking forward for her to join KAUST next year. 

Abdullah's first IEEE transactions paper

posted Jan 11, 2018, 12:53 AM by Khaled salama

Abdullah started his PhD with a bang publishing at the most prestigious microwave circuits journal (IEEE Transactions on Microwave Theory and Technique). In this work we demonstrated an enhanced RF-to-dc converter that selectively limits the conductions of the rectifying transistors depending on the RF power level. As a consequence, the proposed architecture limits the reverse current without degrading the forward current and can operate efficiently for a wider range of RF input power.When operating at the ISM band 433 MHz with a 100-kohm load, the measurement results show a PCE of 86% and a sensitivity of −19.2 dBm, and a PCE of 66% and a sensitivity of −18.2 when operating at the UHF band. The proposed designs provide a high PCE, high sensitivity, wide DR, less sensitivity to the load compared to the state of the art as shown below.

Broad, tunable constant phase angles made easy!

posted Jan 5, 2018, 3:48 AM by Khaled salama

Doctoral student Agamyrat is on fire having his 3rd first author paper accepted in less than 6 months. In this work, MWCNT reinforced PVDF-TrFE-CFE are used to fabricate electrostatic Fractional order capacitors.  Our approach controls the CPA of the FOC in the broad range of -65 to -7 which is the reported maximum CPA dynamic range for a defined 150 kHz to 2 MHz CPZ and allows the manipulation of the pseudo-capacitance value.  In comparison with previous studies, the fabrication process is simplified, and fabrication cost is reduced significantly. The dynamic range of tuning the CPA is also broadened. Finally, the fractional order Hartley-based sinusoidal oscillator is realized, and it is shown that the oscillation frequencies are increased almost 15 times compared to the conventional Hartley-based sinusoidal oscillator counterpart. All in all, we believe that an FOC from CNT-ferroelectric composite paves the way for reliable, robust electronic systems. This work was made possible through a generous grant (RGC/3/2385-01) from the Saudi Basic Industries Corporation (SABIC). More deatils can be found at:  A.

[Hot Paper] Biologically inspired Carbon monoxide sensor

posted Jan 1, 2018, 11:22 PM by Khaled salama   [ updated Jan 1, 2018, 11:34 PM ]

A team from MIT and KAUST developed a new carbon monoxide sensor making use of a molecule that can be voltage-activated using a newly reported method in Angewandte Chemie International Edition ("Bio-Inspired Carbon Monoxide Sensors with Voltage-Activated Sensitivity") and is classified as
hot paper in the area of Gas Sensors.  Michael Burger at Nanowerk writes more about it  (Voltage-activated carbon monoxide sensorand interviews   Vera Schroeder, a Ph.D. candidate in the Swager Group at Massachusetts Institute of Technology (MIT), who, together with Suchol Savagatrup, is the first author of the paper.  
Our sensors function in oxygenated and humid conditions and have sensitivities to meet the limits of detection required by the Occupational Safety and Health Administration (OSHA). While we are competitive in terms of sensitivity and response time with commercial sensors, we did not pursue optimizations in this current report. This work was supported by KAUST sensor project 2015-SENSORS-2719 and the Army Research Office through the Institute for Soldier Nanotechnologies and the National Science foundation (DMR-1410718).
