The world’s smallest e-nose sensor options unmatched odour decision and dense integration utilizing cutting-edge CMOS expertise.

Aroma Bit, Inc.,primarily based in Chuo-ku, Tokyo, develops compact odour sensors and associated revolutionary providers. It just lately unveiled a prototype of an e-nose-type odour imaging sensor. This prototype, constructed utilizing CMOS semiconductors, claims to be the smallest on this planet, that includes excessive integration and superior odour decision.
The corporate has engineered a brand new odour imaging sensor chip utilising CMOS semiconductor expertise. This chip, measuring 1.2 x 1.2 mm, contains built-in peripheral driver and A/D converter circuits. A key a part of the event concerned an indication check in maximising the variety of odour-receptor membranes throughout the confined house of the chip’s sensor aspect space. These membranes had been created utilizing superior printing expertise from SIJ Expertise, recognized for its functionality to supply tiny droplets for ultra-fine dishing out on the micron stage.
This growth has led Aroma Bit to efficiently set up a elementary expertise that accommodates 100 odour-receptor membranes inside a mere 1.2mm x 1.2mm sensor aspect space. Consequently, this has created the world’s smallest e-nose sort odour sensor thus far, boasting the very best density sensor aspect array. With these developments, Aroma Bit is poised to expedite its entry into markets that demand low-cost, high-volume purposes, enhancing sensor integration throughout numerous units.
A few of the key options of the e-nose sort odor imaging sensor embrace:
- Chip Die Dimension: 3.2mm x 3.4mm
- Sensor Space Dimension: 1.2 mm x 1.2 mm
- Sensor Factor: 240 x 240 Sensor Components (57,600 Components)
- Chip-embedded Circuitry: Sensor Driver Circuit / AD Converter Circuit
- Odour Receptor Membrane: 100 membranes deposited
Historically, gasoline chromatography and oxide semiconductor-type sensors have been used to measure odours. Fuel chromatography can determine the precise parts of an odour, whereas oxide semiconductor sensors measure the overall focus of odorants however can’t differentiate between particular person odours. In distinction, the e-nose sort odour sensor mimics the human nostril’s skill to discern odours by making a digital sample of odours. That is achieved by depositing a number of odour receptor membranes with totally different chemical affinities onto numerous sensor components.
