Abstract :
This paper reports on the development of a new integrated laser Doppler blood flow microsensor and its application for monitoring the blood flow of chickens as an important factor in preventing avian influenza infection. To enable the attachment of the blood flow sensor to chickens without making the attachment felt, we have developed the world´s smallest size (1/1000 the weight of a commercial blood flow instrument) and least power-consuming sensor using MEMS technology and wireless 315 MHz band transmission. The developed MEMS blood flow sensor has enabled long-term monitoring of chicken blood flows.
