We developed unconstraint measurement of vital information using near-infrared light sensor for casual sensing of pulse wave information. This sensor is composed of infrared LED and photodiode for measuring the cyclic change of hemoglobin concentration inside blood vessel. This sensor could measure the pulse wave without constraint of human body. Measured data represented near value to the measured...
We propose on-chip monitoring system for production process of platelets in a microfluidic chip. The applied pressure condition to microfludic channel can be controlled. In this study, we demonstrated the on-chip monitoring and confirmed that proplatelet was generated.
It is highly required to long-term monitoring of the biosignals under unbouded and non-invasive condition for health and safe management. Thus, we present biosingnal sensing by the miniaturized load sensing system using a quartz crystal resonator (QCR). We show a method of miniaturization of the sensing system and also measurement results of the biosignal sensing in a chair.
