inesses said the technology sometimes didnt work as advertised.
A radio frequency identification (RFID) chip is added to the sensor so it can communicate wirelessly with a handheld device that would display ethylene levels.
Swager said the price could be as low as 25 cents for the carbon nanotube sensor plus 75 cents for the RFID chip.
Ethylene is a gaseous plant hormone which is responsible for fruit ripening.
How it works
The sensor consists of tens of thousands of carbon nanotubes, which
