Diabetic retinopathy (DR) is the main cause of retinal damage due to fluid leakage from blood vessels. Automated diagnostic systems assist the ophthalmologists practice manual lesi...

Color information is an important tool for diagnosing melanoma. In this study, we used a hyperspectral imager (HSI), which can measure color information in detail, to develop an au...

EEG source imaging aims to reconstruct the neural activities of the brain accountable for the recorded scalp potentials. This procedure requires solving two problems, namely, forwa...

Hyperglycemia is common in critically ill patients and leads to various severe complications and even death. Keeping blood glucose within the range of 80–110 mg/dL (4.4–6.1 mmol/L)...

The use of social network service (SNS) applications for health communication has revolutionized communication between physicians in recent years. We performed an unrestricted retr...

The micro-strains of a fingernail and toenail caused by pulse wave were measured by a conventional strain measuring method using a biaxial strain gauge. The strain fluctuations of ...

Assessing blood flow, as well as blood volume and oxygen saturation, is of utmost importance for health monitoring. Assessing microcirculation, as opposed to macrocirculation, is e...

The ability to fine-tune the movement of swallowing-related organs and change the swallowing pattern to fit the volume of a bolus, texture and the physical properties of the food t...

Ultrasound is a convenient non-invasive imaging modality used for the diagnosis or detection of various diseases and assessment of therapeutic effects. However, when imaging intern...

To evaluate muscle function accurately, it is necessary to simultaneously measure electromyogram (EMG) and mechanomyogram (MMG). We have developed an MMG/EMG hybrid transducer syst...

Percutaneous extracorporeal circulation therapies such as apheresis and hemodialysis are commonly used in intensive care units, hemodialysis centers, and clinically settings. In th...

Magnetocardiography (MCG) is an effective modality for clinical application and health monitoring due to non-contact measurement and mapping of heart activity at high spatial resol...

Cells sense the mechanical properties of their surrounding environment and activate intracellular signaling pathways that play important roles in cell survival, proliferation, diff...

This paper describes the designing of a fourth order low-pass filter (LPF) for portable ECG application. The proposed filter is designed by cascading one P-biquad and one N-biquad ...

A hemoconcentrator is installed as a part of cardiopulmonary bypass to concentrate the blood by removing excess water and unnecessary electrolytes from the blood diluted with myoca...

Electrodes that output electric current as conduction current are widely used to stimulate nerves and cardiac cells in human body. We designed a photoelectric dye-coupled polyethyl...

During walking, arm and leg swings in healthy people are closely coupled temporally by interlimb coordination. A split-belt treadmill contains two belts that can be driven at diffe...

The aim of this study was to measure maximum isometric force under two different conditions: active and passive conditions. The electromyograms (EMGs) were also measured. The elbow...

The arterial baroreflex system is an important negative feedback system that controls arterial pressure (AP) within a normal range during daily activities. We have analyzed this sy...

Recent advances in in vivo neuroimaging have encouraged the development of noninvasive methods using near-infrared (NIR) light. The low resolution images through the skull with tra...
