Research paper : Development of a sensor system for animal watching to keep human health and food safety (T. Itoh et al.)−232−Synthesiology - English edition Vol.3 No.3 (2010) AuthorsToshihiro ItohCompleted the doctoral course at the Graduate School of Engineering, The University of Tokyo in 1994. Joined the Research Center for Advanced Science and Technology, The University of Tokyo, as assistant in 1994, and become lecturer and assistant professor. Joined AIST in 2007. Deputy director of the Research Center for Ubiquitous MEMS and Micro Engineering in 2010. Engaged in research for piezoelectric MEMS, MEMS probe card, MEMS packaging, wireless sensor node, and others. Research Director of the “Development of the Animal Watch Sensor for Safety” of the Core Research for Evolutional Science and Technology (CREST), Japan Science and Technology Agency (JST) since 2006. Engages in research for weaving MEMS as the Director of Macro BEANS Center, Bio Electromechanical Autonomous Nano Systems (BEANS) Project of the New Energy and Industrial Technology Development Organization (NEDO). In this paper, was in charge of the development of the MEMS sensor and the wireless sensor node.Takashi MasudaCompleted the doctoral course in applied electronic engineering at the Graduate School of Electronic Science and Technology, Shizuoka University in 2001. Independent researcher at the Gunma Industrial Technology Center in 2002. Worked as chief researcher of the R&D Center, Taiyo Yuden Co., Ltd. and also as the special appointment lecturer of precision mechanical engineering at the Graduate School of Engineering, The University of Tokyo in 2006 to present. Has engaged in research and development of the elements and signal processing of humidity sensor, silicon piezoresistance pressure sensor, sapphire capacitance pressure sensor, and ball inclination sensor. Currently works on the development Discussions with Reviewers1 Configuration of the wireless sensor nodeComment (Toshimi Shimizu, Research Coordinator (current affiliation: Deputy Director General), AIST)The conceptual points and their degree of importance (or difficulty) of the newly designed wireless node corresponding to an event-driven type are unclear. As a plan, I think you should compare the configurations of the conventional wireless node and the newly designed one, list the issues for each element, and explain the importance (or difficulty) of each. I think that will enhance the understanding of the general readers including engineers who are not familiar with MEMS.Answer (Toshihiro Itoh)Revisions were made in Fig. 6 as you instructed.2 Technical termsComment (Toshimi Shimizu)The National Institute of Animal Health (NIAH) is listed as the joint research institute. As far as the reviewer knows, there are several veterinarians at the NIAH, and from veterinary standpoint, what are the recent research trends for preventing infection of chickens? Please also add some comments from the point of technical policy and measures of the Ministry of Agriculture, Forestry and Fisheries.Answer (Toshihiro Itoh)We added some explanation in the second paragraph “measures at the poultry farm…” in “1 Introduction”.Comment (Toshimi Shimizu)There are several difficult English terminologies for the general readers including engineers. For example, “time-driven”, “preamble”, “parity bit”, “direct conversion”, “custom-made RF-IC”, and “vital signs” are terms that may be used often in your field, but are incomprehensible to general readers. I think you should explain them sufficiently.Answer (Toshihiro Itoh)At least, for the terms you indicated, we added explanations as much as possible at first appearances.[11][12][13][14][15]of the event-driven communication protocol in ultra low power wireless sensor, as well as the development of the piezovibration power generation system, ULP custom LSI, and small antennae for 300 MHz band, at the “Development of the Animal Watch Sensor for Safety” of JST CREST. For this paper, was in charge of the development of the ULP technology and the wireless network system.Kenji TsukamotoCompleted the master’s course at the Graduate School of Agricultural Science, The University of Tokyo in 1982. Joined the National Institute of Animal Health, Ministry of Agriculture, Forestry and Fisheries in 1982. Worked as researcher, chief researcher, head, and senior researcher from 2007. Engaged in epidemiological survey of wild birds for avian influenza and genetic diagnosis method from 2004. Joined the “Development of the Animal Watch Sensor for Safety” of JST CREST as main joint researcher in 2006, and works on the analysis of changes in disease states of chicken infected with bird flu virus, as well as the analysis of molecular basis of avian pathogenesis. In this paper, mainly worked on the experimental infection and the development of the prototype system.sensa), Patent Application 2010-098993 (in Japanese).H. Okada, T. Kobayashi, T. Masuda and T.
