The purpose of this study, which comprised 2 experiments, was to investigate cognitive effects on odor perception. An odor was presented using an olfactometer. In Experiment 1 ("continuous" presentation), anethole, an odor unfamiliar to most Japanese individuals, was presented continuously for 1 session (20 min), whereas in Experiment 2 ("intermittent"(More)
Tissue engineering has been developed with the ultimate aim of manufacturing human organs, but success has been limited to only thin tissues and tissues with no significant structures. In order to construct more complicated tissues, we have developed a three-dimensional (3D) fabrication technology in which 3D structures are directly built up by(More)
This paper presents a new type of ultrasonic gas molecule concentration sensor for rescue robotics and the performance of developed sensor is investigated by applying as human breath gas measurement sensor. This devise can measure the change of the gas concentration with a sampling rate of 400 kHz. Ideal gas experiment results show that the proposed sensor(More)
