An acoustic blood pressure sensing scheme using time of flight and shear wave elastography techniques
(Sensors and Actuators A-Physical, 2021)
A novel wearable blood pressure sensor scheme is presented. The design incorporates an array of piezoelectric transducers to transmit acoustic waves through the skin, and receive reflected echoes from an arterial wall. The ...
Synthesis and characterization of Near-Infrared (NIR)-light triggerable upconverting nanoparticles to enhance activity of immobilized l-asparaginase
(4. EURASIA Biochemical Approaches & Technologies-4.EBAT Conference, 2022)
In this study, PEG-L-ASNase enzyme was immobilized on UCNPs and its activity was improved by NIR. NaYF4: Yb3+, Er3+/PEI UCNPs were characterized to observe structural and morphological changes before/after enzyme immobilization. ...
A turbine-based MEMS sensor for spirometry with wearable devices
(IEEE Sensors Journal, 2019)
This paper presents a turbine-based microelectromechanical systems (MEMS) sensor for spirometry application. The compact sensor dimensions allow integration into smart wearable devices for mobile spirometry without a ...
Encapsulation of diiodo-BODIPY in sodium dodecyl sulfate stabilized cellulose acetate capsules for enhanced singlet oxygen production in aqueous solution
(Wiley, 2023)
As drug delivery vehicles, polymeric capsules have become highly versatile structures to protect the active substrate from degradation, improve biocompatibility, and provide controlled release. In particular, encapsulation ...
Protecting IMSI from fake base stations exploitation and spoofers impersonation in 5G and beyond cellular networks
(2022)
Fifth-generation (5G) mobile networks require authenticated and fully secured transmissions
between user devices and 5G base stations (gNodeB). In the current 5G technology standard, mobile devices
cannot distinguish ...
Hybrid magnetic-piezoelectric energy harvester for power generation around waistline from gait
(Journal of Electrical Engineering & Technology, 2019)

Enhancement of enzyme activity by laser-induced energy propulsion of upconverting nanoparticles under near-infrared light: A comprehensive methodology for in vitro and in vivo applications
(Elsevier, 2024)
If the appropriate immobilization method and carrier support are not selected, partial decreases in the activity of enzymes may occur after immobilization. Herein, to overcome this challenge, an excitation mechanism that ...
Modified MU-STBC with round transmission for improving the date rate and reliability of future 6G and beyond wireless networks
(2023)
In this study, we present a novel multi-user scheme in which space-time block coding (STBC) is exploited for transmitting data in two rounds in a multiple-input multiple-output (MIMO) fashion while orthogonal frequency ...
OFDM-subcarrier power modulation with two dimensional signal constellations
(2019 Innovations in Intelligent Systems and Applications Conference (ASYU), 2019)
An original modulation technique has been recently proposed for wireless communication systems known as OFDM- SPM (OFDM with Subcarrier Power Modulation). This technique utilizes a characteristic of the subcarriers of the ...
A sub-cm3 energy harvester for in-vivo biosensors
(Microelectronic Engineering, 2020)
The development of a kinetic energy harvester for in-vivo applications is reported. Consisting of an untethered magnetic platform encased by two stators, the device converts normal body movements into electrical power. A ...
