This study presents a novel, ultralow-power single-sensor-based electronic nose (e-nose) system for real-time gas identification, distinguishing itself from conventional sensor-array-based e-nose systems, whose power consumption and cost increase with the number of sensors. Our employs single metal oxide semiconductor (MOS) sensor built on suspended 1D nanoheater, driven by duty cycling─characterized repeated pulsed inputs. The sensor's ultrafast thermal response, enabled its small size,...
We developed a thermal conductivity detector-type gas sensor based on suspended 1D nanoheater. The excellent insulation and small size induced by the nano-sized architecture enabled ultrafast detection at ultralow power with pulsed input. Due to these advantageous, thus, nanoheater-based is expected be applicable IoT applications. chip was integrated through-silicon vias adaptive heater fabrication for facile packaging. Moreover, entire chips were fabricated using wafer-level...
Heterogeneous multi-sensor patch devices should meet the requirements of various applications, and an adhesive interposer-based concept with integrated microscale structures is proposed to provide comfortable pressure-based reconfiguration capability where different kinds sensor components are easily attached or detached for application-specific purposes. Furthermore, embedding real-time edge-computing into a miniaturized device conventional legacy microcontroller, interface IC designed...
