SPIROMETER COMPRISING PIEZOELECTRIC SENSOR |
摘要 |
The present invention is directed to a spirometer comprising a piezoelectric sensor and the use of the spirometer in measuring a user's lung performance and/or tracking a user's lung performance over a period of time. The spirometer is configured so that fluid flow through a housing produces oscillating stresses in a piezoelectric material. The oscillating stresses produce an electric signal. Characteristics of the electric signal, such as the magnitude of the signal at particular frequencies, can be measured and used to determine the rate of fluid flow through the housing during inhalation or exhalation. The fluid flow characteristics may then be displayed on a variety of devices, such as a smartphone, a personal computer, etc. |

1. A spirometer comprising
a. a housing having a first fluid opening and a second fluid opening, and b. a fluid flow sensor comprising a piezoelectric material oriented within the housing to produce an electric signal in response to fluid flow through the housing,wherein the spirometer is configured so that fluid flow through the housing produces oscillating stresses in the piezoelectric material, andwherein the electric signal has a magnitude that corresponds with the rate of fluid flow through the housing. |
