MEMS laser Doppler blood flow sensor and its application for preventing bird flu pandemic

Abstract

The chickens infected by bird flu have swelling and hyperemia. it is considered that they have cardiovascular trouble. Therefore, measuring blood flow is important for preventing bird flu pandemic. Then, we developed new laser Doppler blood flow sensor fabricated by MEMS technology to attach to chickens. The new MEMS laser Doppler sensor is four hundredth part of power consumption for conventional laser Doppler blood flow sensor. In the preliminary experiment, the chickens′ blood flow change is successfully observed by attachment of the new MEMS blood flow sensor. The paper reports about the successful result of measuring blood flow for several days.
