In this paper, we describe the development of a solid-type pH sensor with an ultra-low power consumption of $8.2 \times 10^{-4}$ mAh per measurement and a reasonably high accuracy of 0.1 pH for the real-time monitoring of the rumen of a cow. The sensor combines a metal-oxide-semiconductor field-effect transistor with a separate gate as the sensing electrode, and was fabricated using indium tin oxide...
Brain-computer interfaces (BCIs) largely augment human capabilities by translating brain wave signals into feasible commands to operate external devices. However, many issues face the development of BCIs such as the low classification accuracy of brain signals and the tedious human-learning procedures. To solve these problems, we propose to use signals associated with eye saccades and blinks to control...
To realize a next generation strategy for Japanese agriculture and livestock husbandry, especially aiming at developing a high effective electronic management system for cow rearing farmers. We developed a rumen pH sensor which can implement a real-time monitoring of pH value in cow rumen with low power consumption and high accuracy. The prototype of pH sensor was fabricated and packaged, which can...
In this paper, a solid type pH sensor with ultra-low power consumption of 8.2 X 10−4 mAh for each measurement and ultra-high accuracy of 0.01pH was developed for real-time monitoring of cow-rumen. The sensor combines a metal-oxide-semiconductor field-effect transistor (MOSFET) with a separate gate as a sensing electrode, which was fabricated by indium tin oxide (ITO) with an optimized capture structure...
This paper proposes a brand new method for drawing partial discharge fault maps based on polar coordinate for insulation defects of GIS. As different from a traditional plane coordinate map, the polar coordinate map can realize head-tail connection of the power frequency signal phase, so as to better observe the phase distribution of partial discharge pulses with the cycle, especially the symmetric...
Researches on CZT detectors emphasize on how to correct the incomplete charge collection due to the defects in CZT crystals and to improve the performance of CZT detectors. Normally to reduce the surface leakage current and to shape the weighted electric field the guard ring on side wall or on the anode surface surrounding the pixel is applied. Because the guard ring is on the side wall of CZT detectors...
