This multi-functionality eliminates the need for separate specialized devices while maintaining reliable gas sensing.
2Productivity
If comprehensive air quality monitoring is implemented, then real-time monitoring capability is improved, but device cost increases
Solution Approach 1:
The patent employs low-cost nanoscale sensors (MEMS and CNT-based) that can be mass-produced at affordable prices. These sensors are integrated into a compact package that fits within a smartphone housing, making the overall system cost-effective while maintaining continuous real-time monitoring capability across multiple gas types.
Solution Approach 2:
The system monitors multiple gas parameters simultaneously (CO, CO2, H2S, VOC concentrations) using a unified sensor architecture. By changing the sensing approach to nanoscale technologies, the system achieves comprehensive multi-parameter monitoring at reduced cost compared to traditional separate sensor systems.
3Ease of manufacture
If nanoscale sensors are integrated with mobile devices, then affordability and portability are improved, but sensor size and complexity are reduced
Solution Approach 1:
The sensor package is nested within the smartphone housing, with multiple sensors (CO, CO2, H2S, VOC) integrated into a compact arrangement. The sensor package fits inside the mobile electronic device housing, allowing the system to maintain portability while achieving comprehensive monitoring through the nested integration of multiple sensing elements.
