Life expectancy in most countries has been increasing continually over the several few decades thanks to significant improvements in medicine, public health, as well as personal and environmental hygiene. However, increased life expectancy combined with falling birth rates are expected to engender a large aging demographic in the near future that w...

Advancements in medical science and technology, medicine and public health coupled with increased consciousness about nutrition and environmental and personal hygiene have paved the way for the dramatic increase in life expectancy globally in the past several decades. However, increased life expectancy has given rise to an increasing aging populati...

Electrocardiography (ECG) is the most common and extensively used vital sign monitoring method in the modern healthcare systems. Different designs of ambulatory ECG systems were developed as alternatives to the commonly used twelve-lead clinical ECG systems. These designs primarily focus on portability and user convenience, while maintaining signal...

Over the past few decades, we have witnessed a dramatic rise in life expectancy owing to significant advances in medical science and technology, medicine as well as increased awareness about nutrition, education, and environmental and personal hygiene. Consequently, the elderly population in many countries are expected to rise rapidly in the coming...

Advancements in the micro-electromechanical systems technology have enabled the realization of small-size, high-performance inertial motion and magnetic field sensors that are embedded in most modern-day smart gadgets. These sensors, when coupled with the high-speed computing and communication technologies may potentially enable in-home monitoring...

The global population is aging due to increased life expectancy and declining birth rates. As a result, there is a growing prevalence of chronic diseases such as heart disease, hypertension, and diabetes, among the older population. These conditions not only diminish the quality of life, but also significantly drive up healthcare costs. Consequentl...

Humankind in today's world faces a plethora of unprecedented challenges across environmental, public health, financial, and social domains. From the rapid deterioration of the environment and climate situation driven by greenhouse gas emissions to the persistent threat of severe public health crises such as Ebola, H1N1 flu, and the recent COVID-19...

Neuromarketing is an emerging research field that aims to understand consumers’ decision-making processes when choosing which product to buy. This information is highly sought after by businesses looking to improve their marketing strategies by understanding what leaves a positive or negative impression on consumers. It has the potential to revolut...

The rapid advances in high-speed and low-power computing, communication, and sensor technologies have propelled the growth of Internet-of-things (IoT) technology. IoT enables sensors, actuators, and devices working together in applications such as a smart home to track the health, activity, comfort, and well-being of residents, thus potentially rev...

Fluorescent carbon nanoparticles (FCNs) have emerged as promising sensitizers for dye-sensitized solar cells (DSSCs) owing to their unique optical properties and low-cost fabrication. In this study, we synthesized three different types of FCNs, such as hydrogen peroxide (H2O2)-assisted FCNs (FCNH), hydrothermal-assisted FCNs (FCNA), and pyrolysis-a...

Wearable health monitoring devices allow for measuring physiological parameters without restricting individuals’ daily activities, providing information that is reflective of an individual’s health and well-being. However, these systems need to be accurate, power-efficient, unobtrusive and simple to use to enable a reliable, convenient, automatic a...

Throughout human history, deadly infectious diseases emerged occasionally. Even with the present-day advanced healthcare systems, the COVID-19 has caused more than six million deaths worldwide (as of 27 July 2022). Currently, researchers are working to develop tools for better and effective management of the pandemic. “Contact tracing” is one such...

Background Thousands of Coronavirus Disease 2019 (COVID-19) patients have been discharged from hospitals Persistent follow-up studies are required to evaluate the prevalence of post-COVID-19 fibrosis. Methods This study involves 462 laboratory-confirmed patients with COVID-19 who were admitted to Shenzhen Third People’s Hospital from January 11, 2...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic since early 2020. The coronavirus disease 2019 (COVID-19) has already caused more than two million deaths worldwide and affected people's physical and mental health. COVID-19 patients with mild symptoms are generally required to self-isolate and monitor for symptoms...

In recent years, there has been a growing interest in smart e-Health systems to improve people’s quality-of-life by enhancing healthcare accessibility and reducing healthcare costs. Continuous monitoring of health through the smart e-Health system may enable automatic diagnosis of diseases like Arrhythmia at its early onset that otherwise may becom...

Recent advances in micro-electromechanical systems technology have enabled the evolution of miniature, low-power, and high-performance inertial motion sensors that are commonly found in most present-day smart gadgets. Furthermore, high-speed and power-efficient communication and computing technologies may enable these sensors to potentially pave th...

Maintaining good mobility with ease and freedom of movement is important for an individual’s health and active aging. The knee joint, being the primary bearer of the body weight, plays a vital role in mobility. Continuous monitoring of the knee joint can potentially provide important information related to knee health and mobility which can be used...

The world's population is aging: the expansion of the older adult population with multiple physical and health issues is now a huge socioeconomic concern worldwide. Among these issues, the loss of mobility among older adults due to musculoskeletal disorders is especially serious as it has severe social, mental and physical consequences. Human body...

The aging population is projected to rise significantly due to continuous improvements in healthcare, personal and environmental hygiene, nutrition and education. This large aging demographic may cause adverse socio-economic impacts in terms of the costs associated with healthcare and social services. In order to support the healthcare needs of the...

We discuss the source of random telegraph signal (RTS) behavior in photodiodes, metal-oxide-semiconductor (MOS) transistors and active pixel sensors (APS). First, a detailed review on the magnitude and the time constants of RTS noise observed in state-of-the art small-pitch imagers will be presented. Second, the impact of RTS noise on the quality o...

The introduction of the digital image sensor has triggered a revolution in the field of imaging. It has not only just replaced the conventional silver halide film based imaging system, but has also enormously widened the scope of imaging applications. Previously, charge-coupled devices (CCDs) were the most popular technology for image sensors. But...
