This paper reports on a microelectromechanical systems (MEMS)-based sensor for pulse
wave measurement. The sensor consists of an air chamber with a thin membrane and a 300 …

Pulse wave monitoring is critical for the evaluation of human health. In this paper, a
wearable multi-sensor pulse wave monitoring system is proposed and demonstrated. The …

Bodily pressures can provide valuable information for making a diagnosis or health
monitoring. The pressure sensor is widely used to obtain bodily pressure, however, sensor …

Wearable sensor devices with minimal discomfort to the wearer have been widely
developed to realize continuous measurements of vital signs (body temperature, blood …

This article investigates a prospective capacitive sensing method for the measurement of
physical characteristics of a pulsatile liquid flow. It was tested on a physical vascular model …

In recent years, with the continuing progress of aging social infrastructures such as bridges
and tunnels, there has been high demand for the assessment of deterioration of their …

This paper reports a sensor that can measure blood pulse waves with high sensitivity. The
sensor has a piezoresistive cantilever which is designed to measure the pressure change of …

This paper reports on a MEMS vibration sensor with a structure of liquid on a thin Parylene
membrane which has a piezoresistive beam attached underneath. The proposed sensor has …

Piezoelectric materials show great promise for low-power wearable and implantable
sensing, but their rigidity makes it challenging to integrate them with biological tissue. To …

We have engaged in researching and developing a large number of sensor devices using
piezo-resistive cantilevers. The important technical features of our sensor devices lie in their …
