    Design and implementation of wireless patient health monitoring system
    (American Institute of Physics Inc., 2023) Saud, Al-Humairi, S.N.; Faizlin, M.K.B.A.; Saud, A.N.
    The design and deployment of an e-health monitoring network system are demonstrated in this paper. This system uses smart devices and wireless sensor networks in the real-time study of numerous patient data. Patients can be monitored via telemonitoring with this system, which intends to make diagnosis easier for clinicians. It also makes it easier for doctors and caregivers to keep continuous monitoring of their patients in any critical situations. To monitor the patient's health and surroundings, various medical and environmental sensors were employed, such as temperature, blood pressure, pH level and SPO2 sensors. The measured data have transmitted in real-time through a server/cloud. For privacy and security, the designed architecture of this project was used to keep a closed observation on a home patient case and many patients in health care units or public health hospitals. Furthermore, the readings can also be viewed on the webpage called "ThingSpeak"whereas the webpage is connected to the data cloud and displays the patient's readings via a visualizer in graph real-time form. In conclusion, this system shows a higher efficiency in data measurement and server transmission; thus, it can reduce the service time and expense required. © 2023 Author(s).

    Tribological behavior of porous Ti-56.07wt.% Ni shape memory alloys: Towards a sustainable biomaterials
    (American Institute of Physics Inc., 2023) Saud, Al-Humairi, S.N.; Anthony, M.C.; Saud, A.N.; Ganesan, T.; Erkan, K.
    Due to its high strength, stiffness, and biocompatibility, titanium alloys are employed in biomedical applications, although their wear resistance is still inadequate. Porous TiNi structures have a lower elastic modulus and density than dense TiNi structures, but they have sufficient shape memory characteristics, making them suitable for power absorption, lightweight, and biomedical implants. This study investigates the porous Ti-Ni Shape memory alloys (SMAs) tribological behavior for sustainable biomaterial's purposes. The ball-on-disk wear approach with a stainless-steel counter ball was conducted at different speeds times and applied loads to reveal the surface degradation of the Ti-Ni SMAs. The experimental procedure was designed via the Taguchi approach as a design of experimental (DoE) model. The wear mechanisms were inspected according to the wear loss, friction temperature, and worn surface feature. The results revealed that the wear rate and ball depth increased as the speed, time, and applied loads increased. However, the friction temperatures fluctuated according to the wear testing parameters due to the same percentage of the surface samples' surface porosity presence. © 2023 Author(s).
