Micro-Machined Stent-Type Flow Sensor for Evaluation of ...

We present a thermal flow sensor that is suitable for measuring nasal respiration. To fix the flow sensor inside the nasal passage, we integrated it onto a stent structure, which is normally used as a medical device. The sensor was monolithically integrated on the Ti substrate by applying photolithography and wet etching processes. The developed fabrication has advantage that it is able to ...

Development of tube flow sensor by using film transfer ...

· A micro-electro-mechanical systems flow sensor was integrated onto an optical fiberscope to enable in situ breathing and surface image evaluations in small airways. The tube flow sensor was developed to be easily attached to an optical fiberscope. Firstly, two heaters working as flow rate sensors were formed on thin film by using a lift-off process.

· The nasal pressure can be measured using a pressure micro sensor placed near or inside the sealed nose. The measured nasal pressure is proportional to the tracheal airflow rate for a given tracheal diameter. Assuming the diameter of the trachea for each subject remains constant, the flow rate can then be estimated from the nasal pressure. Calculations to estimate the pressure variation within ...
