Apparatus for detecting human's breathing
First Claim
1. A device for detecting gas and aerosol inhaled and exhaled by human body, comprising of:
- (1) a substrate, which is used to carry gas and aerosol sensor unit, electronic circuit module, wireless transmitting/receiving module, power supply and a structure for hanging around the nose wall;
(2) at least one carbon nanotube sensor unit, which is used to react with the gas and aerosol to be detected;
(3) an electronic circuit module, which is installed with electronic circuit layout and is connected to said substrate, said carbon nanotube sensor unit and wireless transmitting/receiving module to perform a special processing on the electrical signal obtained from the measurement of electrical property of said carbon nanotube sensor device;
(4) a wireless transmitting/receiving module, which is used to receive the gas and aerosol signal converted from said electronic circuit module and wireless transmitting method is used to transmit the signal to warning module or monitoring module; and
(5) a power supply, which is electrically connected to said electronic circuit module so as to provide power to said electronic circuit module and said wireless transmitting/receiving module.

Abstract
An apparatus applied to detect the human breath gas, including a substrate which carries a circuit module, a CNT-based (carbon nanotube) gas sensing element, a wireless transmission/receiver module, and a power supplier, etc. and a clamp structure that could be clamped on the columella between the nostrils. The detectable gas also includes the bioaerosol in the gas. The CNT-based gas sensors react with the breath air and detect whether the specific gas and bioaerosol in the air or not while breathing in and out and the temperature of the air could be measured. This invention can measure the electric response of the CNT-based gas sensor, process the signal by the circuit module and transmit the processed signal to the wireless receiver by wireless transmission/receiver module. And the wireless signal receiver will differentiate the species, concentration and temperature of the gas and provide a warning signal while the specific gas or bioaerosol is detected. The apparatus is portable and has the functions of rapid response and high sensitivity.
