The purpose of this study was to demonstrate the usefulness of a small inertia sensor for quantitativeclassication of movement disorders based on the change in mechanical energy i...

Asthma is a chronic respiratory disease, in which symptoms appear or intensify suddenly, even when patients are being monitored by doctors. Continuous measurement is important to m...

It has been reported that increased intermittent non-Gaussian fluctuations in the instantaneous amplitude of low-frequency heart rate variability (LF-HRV) are related to high morta...

Simulation using computational methods is well-established for investigating mechanical and haemodynamic properties of blood vessels, however few groups have applied this technolog...

We developed an excretion monitoring system equipped with non-contact temperature sensor and a semiconductor gas sensor installed under a toilet seat. The gas sensor is able to det...

We have developed a brain-machine interface (BMI) rehabilitation system for patients with stroke and motor paralysis, which provides proprioceptive feedback upon successful generat...

A new Hill-type model of skeletal muscle contraction referred to as the “SL/ST model” is proposed based on recent physiological findings: intact human skeletal muscles operate on t...

We studied the effects of interactive pressure on the delivery of hydrophobic rhodamine B to ex vivo heated artery walls to determine the optimal drug delivery conditions. The heat...

We investigated the delivery of rhodamine B and Oregon Green®-labeled paclitaxel (OGLP) in ex vivo porcine carotid artery wall (CAW) samples after heating the reagents to 50–70℃ fo...

Individual capacity of recall memory varies greatly even among healthy young adults. Nevertheless, the difference in brain circuitry underlying varied memory capacity has yet to be...

Measurement of instantaneous orthostatic heart rate change has been used as a screening method for care or rehabilitation for the elderly, because it allows evaluation of the auton...

Aortic wall changes dimensions and mechanical properties in response to mechanical stimulation. As these changes are driven by the cells inside the wall, and their mechanical respo...

Some systems to measure voided volume and flow rate have been developed. Clinically, urination parameters are measured using uroflowmeters that have special receivers such as cups ...

Because radiofrequency (RF) coils used in magnetic resonance imaging (MRI) are specific for given regions of interest in the human head (HH), it is necessary to adjust the capacita...

In this paper, we propose an algorithm to construct a spatiotemporal statistical shape model (SSM) of the brain surface of a human embryo. Our model is based on level sets and the ...

An extracorporeal membrane oxygenator (ECMO) is used for the management of severe heart or respiratory failure. In the conventional ECMO system, centrifugal blood pumps are commonl...

We have proposed and developed a vibratory microinjection system (VMS) to facilitate gene transfer and to increase the efficiency in production of transgenic animals. The VMS injec...

We examined muscle stiffness at various pedaling rates under conditions of constant power output. Eight healthy young participants pedaled a cycle ergometer at a power output of 47...

AI-based medical and healthcare devices and systems have unique characteristics including 1) plasticity causing changes in system performance through learning, and need of creating...

Surface electromyographic (EMG) signals are known to be strongly influenced by anatomical, physiological and detection system parameters. Among the detection system parameters, we ...
