Abstract
Official abstract text for this publication.
The gas measurement device includes a filter unit including a plurality of terminals configured to be applied a voltage or a current and a filter configured to vibrate in response to the voltage or the current being applied to the plurality of terminals and a gas sensor configured to detect gas molecules passing through the filter and output a measurement value corresponding to the detected gas molecules.
First claim
Opening claim text (preview).
What is claimed is: 1 . A gas measurement device, comprising: a filter unit including a plurality of terminals configured to be applied a voltage or a current and a filter configured to vibrate in response to the voltage or the current being applied to the plurality of terminals; and a gas sensor configured to detect gas molecules passing through the filter and output a measurement value corresponding to the detected gas molecules. 2 . The gas measurement device according to claim 1 , further comprising a plurality of filter units including the filter unit, wherein the plurality of filter units is disposed to overlap each other. 3 . The gas measurement device according to claim 1 , wherein a pulse voltage is applied to the plurality of terminals, and the filter unit includes a piezoelectric element electrically connected to the plurality of terminals, and the filter is supported by the piezoelectric element. 4 . The gas measurement device according to claim 1 , wherein the current is applied to the plurality of terminals, and the filter unit includes a metal member electrically connected to the plurality of terminals, and the filter is supported by the metal member. 5 . A gas measurement system, comprising: a gas measurement device comprising: a filter unit including a plurality of terminals configured to be applied a voltage or a current and a filter configured to vibrate in response to the voltage or the current being applied to the plurality of terminals; and a gas sensor configured to detect gas molecules passing through the filter and output a measurement value corresponding to the detected gas molecules; and a control unit configured to apply the voltage or the current to the plurality of terminals such that the filter vibrates at a predetermined frequency. 6 . A gas measurement method, comprising: vibrating a filter; and detecting gas molecules that have passed through the vibrated filter and outputting a measurement value corresponding to the detected gas molecules.
