This is because high stress causes not only lowered resistance to illnesses but also estrus failure. Both electrocardiographic monitors and photoplethysmographic (PPG) sensors can measure stress intensity. The electrocardiographic monitors, which can accurately measure the rate and rhythm of heartbeats, are useful to detect stress intensity. However, long-term usage is not suitable due to its operating with electrodes. On the other hand, PPG sensors can be attached to the cow’s tail for long term monitoring. Thus, we have developed wearable type PPG sensors and attempted to detect stress intensity..|

Sawada, Multifunctional optical sensor module Integrate1d optical micro displacement sensor and its application to a
photoplethysmographic sensor with measuring contact force, BIOSTEC2018 , 2018.01, Photoplethysmography (PPG) is widely and commonly used, as it produces a wide range of information, such
as stress level, heart rate interval, respiration rate, blood vessel hardness, etc. It is necessary to control the
contact force between a PPG sensor and the measurement location (the skin surface), in order to obtain an
accurate PPG signal. We propose new multifunctional sensor modules that can measure both pulse waves and
contact force. The sensor module has a micro integrated displacement sensor chip with an optical source,
photo diodes, and op-amp circuits, and a gum frame with a mirror. Some incident light penetrates into a finger,
and the scattered light, which contains a biological signal (a pulse wave), is detected by one photodiode. The
photodiode can also detect reflected light from a mirror, which is displaced by a contact force. In this paper,
we fabricate a multifunctional sensor module and attempt to simultaneously measure the pulse wave and
contact force. .

Animal health monitoring system can achieve early detection and prevention of diseases and thus reduce economic losses. The wireless sensor nodes attached to animals, in conjunction with a wireless health-monitoring system, detect initial fever, abnormal activity, or stress level of the animals. In this study, we have focused on developing wireless pulse wave sensor to detect stress levels..|

The sensor consisted of a vertical-cavity surface-emitting laser (VCSEL), a photodiode (PD), an Op-amp, a resistor, and a capacitor.

|6.||野上大史、白石隆太、井ノ上涼、澤田廉士, Laser Doppler blood flowmeter for animal health monitoring system, The 7th Japan-China-Korea Joint Conference on MEMS/NEMS2016, 2016.09, The estrus intensity detection of the cow is one of the important purposes for animal health monitoring system. During the time of estrus the engorged vagina can be observed from the outside. The engorged vagina is possible to cause blood flow change. To detect the estrus intensity, we have developed the laser Doppler blood flowmeter sensor element. The sensor element is 3.5 x 5.5 x 1.8mm, which is enable to fabricate wearable wireless sensor node. Using the sensor nodes, we could measure blood flow of the cow in short time. However, measurement of the blood flow was not stable in long term. The cause of the unstable measurement was that the blood flow was sensitive to the contact force between cow’s skin and sensor. The contact force easily changed depending on method of mounting or wagging cow’s tail. In this paper, we incorporated the laser Doppler blood flowmeter sensor element with the force sensor to simultaneously measure the blood flow and the contact force. As a result, we could observe stable measured value of the blood flow and pulse wave at the stable contact pressure. At the unstable contact pressure, the measured value of underwent a lot of changes. In addition, the pulse wave couldn’t be observed. Thus, we propose that the measurement of the blood flow need to correct for the influence of the contact force..|

|11.||野上 大史, Temperature sensor for an early diagnosis system of pneumonia in calves, The 3rd Singapore-Japan Research Exchange Seminar, 2014.12, Calves are less able to fight virus or bacterium, and predisposed to respiratory disease such as pneumonia. The death and disease accidents caused by respiratory disease are the highest in all accidents. The effective means for early detection of the respiratory disease are to measure rectal temperature with a thermometer. However the mean cannot be frequently conducted on account of spending too effort in the farm. As a means of requiring little effort, we have developed wireless sensor nodes. The primary advantages of the sensor nodes are flexible and slightly temperature sensor pats. The temperature sensor was mounted on the flexible substrate, and the thickness was 0.8 mm. Thus, we can easily attach the sensor nodes to the base of the calf’s tail, which is one of the highest skin temperature parts, and success to measure the skin temperature..|

In previous work, to monitor rumen condition, the wireless sensor node can evaluate the rumen condition with pH measurement system. But the sensor nodes cannot be used for two or three months limited by the volume of the internal liquid of the reference electrode. Also, the sensor nodes are very big along of the internal liquid, which can be though given by mouth of the cow. Thus, we work a new method to monitor rumen
condition with 3-axis acceleration meter. We fabricate the wireless sensor nodes built into 3-axis acceleration meter. Using the sensor nodes, we compare the rumen motility of the force transducer measurement with the 3-axis acceleration data of our sensor nodes. As a result, our sensor nodes can detect sign of the
ruminal typany. In addition, the optimum frequency of the measurement and transmitting turns out 5 seconds. Then, the power consumption is 0.18mA, and the theoretically period of use is 600 days over. Thus, we succeed to develop the wireless sensor nodes which can detect rumen sickness for long term..
