Human exhaled air energy harvesting with specific reference to PVDF film

摘要: Abstract Spirometer is a medical equipment used to measure lung capacity of human being. It leads diagnosis several diseases. The researchers worked on harvesting energy from exhalation while carrying out measurements using spirometer. A prototype has been developed piezoelectric material i.e. PVDF (polyvinylidene fluoride) film as sensor. This paper presents the methodology and experimentation carried for exhaled air film. Experimental results obtained are encouraging. Measurements also various subjects having different height, weight, age gender. Data analysis shows variation in harvested with physical parameters Experimentation that voltage generated due promising harvesting.
