Ethylene gas sensor for evaluating postharvest ripening of ...

· It is widely known that ethylene treatment is an effective method for postharvest handling of fruit. In this study, we employed a field effect transistor based on silicon carbide (SiCFET) gas sensor for detecting ethylene produced from fruits. The characteristics of the sensor was evaluated regarding several parameters. The selectivity and sensitivity of SiCFET sensors can be controlled ...

How ripe is your produce? This sensor can tell you

· The new sensor is composed of carbon nanotubes and a metal catalyst called palladium, which, upon interaction with ethylene, undergoes a process called Wacker oxidation. Through this process, palladium temporarily gains electrons that it passes to the carbon nanotubes, filling up the empty holes in the electronic structures and making them more conductive. By measuring the resulting …

· The sensor responds to ethylene within a few seconds of exposure, and once the gas is gone, the sensor returns to its baseline conductivity within a few minutes. “You’re toggling between two different states of the metal, and once ethylene is no longer there, it goes from that transient, electronrich state back to its original state,” Fong says.

A New Nanotubebased Chemoresistive Sensor for Ethylene

The new sensors, described in the journal Angewandte Chemie [see below], can detect tiny amounts of ethylene, a gas that promotes ripening in plants. Swager envisions the inexpensive sensors attached to cardboard boxes of produce and scanned with a handheld device that would reveal the contents'' ripeness. That way, grocers would know when to put certain items on sale to move them before they ...

SBIR Phase I: Ethylene Sensor for Monitoring Produce ...

Handheld ethylene sensors (typically electrochemical) have recently become available, but their prices of ca. 1,000 are prohibitively expensive for most food sensing applications. As a result, companies in food production, storage, transport, and retail, are interested in the ethylene sensors. Additionally, sensor companies (general and in the food sector) who do not have ethylene sensing ...
