Extracellular volume fraction mapping (ECV Map) can provide quantitative measurements of myocardial tissue with amyloid deposition and myocardial edema. ECV measurements have been ...

In this work, we developed a measurement system that uses LEDs to estimate multiple components such as urea and creatinine in spot urine samples using near-infrared spectroscopy, c...

Evaluation of the impeller radial stability is important from the bioengineering point of view in the development of mechanical circulatory support devices (MCSDs) for safer use as...

Gait characteristics vary among people and correspond to individual differences of external and internal traits. Recent studies on autism spectrum disorders (ASD) reported that gai...

Simultaneous measurements of mechanomyogram (MMG) and electromyogram (EMG) may be useful for accurate evaluation of skeletal muscle contraction. However, unlike the EMG, the MMG is...

As the pathological characteristics of living tissue generally correlate with tissue stiffness, techniques such as ultrasound elastography play an important role in the medical fie...

Electrocardiograms (ECGs) captured by wearable ECG devices readily contain artifacts due to measurement faults. Since artifacts and R waves have quite similar frequency characteris...

The liver plays a central role in all metabolic processes in our body. Currently, orthotropic liver transplantation is the only proven effective treatment for serious acute liver f...

The safety of physically disabled persons must be considered during the initial developmental stages of a rehabilitative or assistive device to prevent death or injury. Thus, in th...

High intensity focused ultrasound (HIFU) is one of the promising minimally invasive therapeutic methods. Focused ultrasound creates coagulation area with minimally invasiveness. Re...

We investigated why movement of the human eye enables us to swiftly find a target symbol out of many alternatives. To this end, we obtained experimental gaze step data, defined as ...

Microfluidic devices are powerful bioapplication tools for cellular experiments in particular, as they can regulate physical and chemical parameters such as the flow rate, shear st...

The present study proposes control target for the motion of an active self-feeding spoon by analyzing skilled spoon motions reflecting the grasping actions of healthy people eating...

Transcutaneous energy transmission systems (TETS), which use electromagnetic induction to wirelessly transfer energy, have been widely used as energy transmission systems for artif...

This paper proposes a specific method of balance control learning at a half-rising posture using an assistive system for improving the pulling chair movement, and reports a case st...

Background and Objective: Acute vasoreactivity testing using inhaled nitric oxide (NO) is performed to determine the treatment strategy in patients with pulmonary hypertension. Ope...

Objectives: Foot problems are common in the elderly and are associated with impaired lower limb muscle strength, reduced balance function, and foot pain. We investigated the effect...

In recent years, a rapid increase in bacterial strains resistant to modern antibiotics has been observed. This alarming rise in drug-resistant organisms has emphasized the importan...

In this study, we used a small implantable complementary metal–oxide–semiconductor (CMOS) imaging device developed by our research group to estimate the blood flow changes by focus...

Development of direct neural interface (DNI) including visual prostheses absolutely requires confirmation of their long-term safety and stability. Functional evaluation by electric...
