Renesas Electronics developed the basic technology for the development of a semiconductor to detect murrain. A small chip loaded with senor is put on the back of a cow, and it transmits the motion abnormality and temperature analysis of the cow wirelessly. It is expected to be helpful for early detection of foot-and-mouth disease and bird flu. The company plans to conduct substantiative experiment with universities and IT-companies and put the chip on the market in 2014.
The developed chip is one centimeter square, and it loaded with a microprocessor that converts the data coming from the senor to frequency for analysis. It detects the abnormality of such parts as body inclination and fever heat with reference to several hundred frequencies and wave patterns it stored beforehand. Communication load is reduced by providing the chip with the analysis function and transmitting a large amount of data the chip obtained to the host computer. At present, visual observation is widespread to detect a diseased livestock, but observation of each cow with the help of this new chip will prevent the disease from spreading fast. Renesas Electronics plans to develop a system to support large-scale livestock farmers jointly with IT-companies.
