The origins of Sensors and Materials go back to the early 1970s when the founding editor of the journal, Professor Kohji Toda, who was working at Stanford University as a visiting scientist, met ... Read More

Speak, Memory is the title of the well-known autobiography by Vladimir Nabokov.(1) It was the first thing that came to mind when Professor Ishida asked me of my recollections of the early days of ... Read More

Impact force identification from structural dynamic responses at certain points on a mechanical structure subjected to impact is a classical inverse problem in dynamics. There has been a growing ... Read More

In this study, we experimentally demonstrated that a high-sensitivity fiber sensor can be used for the remote sensing of temperature and stress simultaneously. The proposed sensor includes severa ... Read More

A novel tissue hardness measurement sensor (tactile sensor) capable of measuring the material constants of sensed objects has been fabricated and demonstrated in this study. The tactile sensor we ... Read More

Enhanced fluorescence using an optical interference mirror (OIM) slide consisting of a metal film and a transparent dielectric thin film is used to improve the sensitivity of a DNA microarray. Tw ... Read More

There are a variety of methods to detect odorant molecules, including gas chromatography (GC) and its related coupled techniques, electronic noses, and olfactory receptor (OR)-based biosensors. N ... Read More

A novel calorimetric biosensor is developed by recirculating flow injection analysis. The biosensor consists of a peristaltic pump, two switching valves, a thermostat, an injection valve, two twi ... Read More

A displacement-sensing scheme is presented herein by utilizing near-field coupling between multiple coils. The sensing system consists of the stationary part and removable sensor tag. The change ... Read More

The dependence of the center reflection wavelength shift of a resin-embedded fiber Bragg grating (FBG) on the resin material was investigated for the use of the grating fiber as a bending deflect ... Read More

A disposable microfabricated Na+-ion-sensing device was developed for the direct on-site measurement of the Na+-ion concentration in live plants. To conduct reliable measurements, silver chloride ... Read More

In this paper, we propose a CMOS image sensor that uses a gate/body-tied p-chnnel metal oxide semiconductor field effect transistor (PMOSFET)-type photodetector for highspeed binary operation. Th ... Read More

The incidence of heart disease increases with age. The typical method of monitoring arrhythmia is to use a body-patch-type sensor with a wet electrode. Even though this sensor is easy to use, it ... Read More

We demonstrate the celluloid-based biochip for cell trapping, prepared by Suzuki's universal microprinting (SUMP) method. The structure of 8 × 8 µm2 micoenclosures consists of a micropillar arr ... Read More
