Low-voltage and low-power optimization of micro-heater and its on-chip drive circuitry for gas sensor array

A matched-profile method for simple and robust vapor recognition in electronic nose (E-nose) system

“…due to its ability of characterizing odors, vapors, and gases [1]. Recently, various composites from carbon-black (CB) and organic polymers are developed as gas sensors for portable use due to its chemical diversity by the selection of proper organic polymers and improved operability with lower power consumption than the metal oxide gas sensors [2,3]. With the help of these improvements in portability and ease of use, the E-nose is widening its potentials in environmental and pollution monitoring, i.e., real-time identification of contaminants, analysis of fuel mixture, detection of oil leaks, testing ground water for odors, and identification of toxic waste, etc.…”

Low power consumption micro C2H5OH gas sensor based on micro-heater and ink jetting technique

“…Due to the difficulties in MEMS technique and higher production cost for micro gas sensor, few commercial devices are selling by pioneering company. This technology needs further improvement in handling device wafer and sensor fabrication processes including packaging process [18][19][20][21][22][23][24].…”

CMOS microhotplate sensor system for operating temperatures up to 500°C

“…Full monolithic integration has been projected by several groups [8,11,12] and has been recently demonstrated [13][14][15].…”
