| Outline of Final Research Achievements |
MEMS technologies were applied for producing the in-situ measurement system that could be used to detect both breathing and optical surface image properties at the small airways. The response time value of the flow sensor was shortened to less than 52 ms by decreasing the thermal capacity of around the heater. Then the thermal flow sensor was integrated onto a basket forceps to fix the flow sensor onto the inside surface of the airway. The basket-forceps-type flow sensor was applied in an animal experiment in which it successfully detected the breathing properties in the airway of a rat. Finally, the tube flow sensor was developed to be easily attached to an optical fiberscope. The fabricated tube flow sensor was attached to the outside of a fiberscope with 1.6 mm in diameter, and it was inserted into a tube that was connected to the airway of a rat. An optical image in the tube was captured, and its breathing airflow rate was successfully detected.
