In brain studies, the function of the cerebrospinal fluid (CSF) awakes growing interest, particularly related to studies of the glymphatic system in the brain, which is connected with the complex system of lymphatic vessels responsible for cleaning t

In medical near-infrared spectroscopy (NIRS), particularly in the study of the brain, light illumination is commonly realised by lasers or laser diodes (LD). However, the rapid development of high-power light-emitting diodes (HPLED), increased optica

As the number of elderly people rises, relatives' care-taking responsibilities increase accordingly. This creates a need for developing new systems that enable relatives to keep track of aged family members. To develop new mobile services for elderly

Electrophysiological recordings from a single or population of neurons are currently the standard method for investigating neural mechanisms with high spatio-temporal resolution. It is often difficult or even impossible to obtain stable recordings be

This paper describes and tests two prototype series of pressure transducer arrays based on electromechanical film (EMFi). By offering high (/spl sim/T/spl Omega/) resistance, EMFi is an excellent material for low-current long-term measurement applica

The self-mixing effect in a diode laser and the Doppler technique are used for quantitative measurements of the cardiovascular pulses from radial arteries of human individuals. 738 cardiovascular pulses from 10 healthy volunteers were studied. The Do

The electrocardiography (ECG) signal is often used as a reference signal when calculating pulse transit times (PTT) measured by photoplethysmographic (PPG) sensors. In addition, ECG measurements are widely used in clinical health monitoring. In clini

Wireless health monitoring can be used in health care for the aged to support independent living, either at home or in sheltered housing, for as long as possible. The most important single monitoring need with respect to security and well-being of th

Wireless health monitoring systems are suggested for use in the health care of the elderly to enable independent but secure living for as long as possible. Activity monitoring is highly valued by welfare and health personnel because it gives an overv

This paper presents experimental measurements conducted using two noninvasive fibre optic methods for detecting heart pulse waves in the human body. Both methods can be used in conjunction with magnetic resonance imaging (MRI). For comparison, the pa
