Abstract
This disclosure describes techniques to improve the range and sensitivity of indoor air sensors. Biomimetic designs are utilized for the input and output ports in the sensor device to improve air flow. The sensor device includes a large intake diaphragm that creates smooth laminar air flow into the device. Exhaust diaphragms are provided to force turbulent air away from the intake port. A bellows style pump is provided to pump air into the sensor device and across the sensor chip. The air is moved through vents at a suitable frequency, e.g., 5 Hz. The performance of the biomimetic air quality sensor device is superior to passive sensor devices as well as fan-enabled devices that continuously allow for air motion. The biomimetic air quality sensor device can be utilized in standalone sensor devices, health monitoring systems, heating, ventilation, and air conditioning systems (HVAC), etc.
