Vinay Pagay holds a "lab on a chip" that measures moisture levels in soil and can be embedded in plant stems for accurate information on water stress. The researchers hope to mass produce the chips for as little as $5 each.
(Phys.org) —Crop growers, wine grape and other fruit growers, food processors and even concrete makers all benefit from water sensors for accurate, steady and numerous moisture readings. But current sensors are large, may cost thousands of dollars and often must be read manually.
Now, Cornell researchers have developed a microfluidic water sensor within a fingertip-sized silicon chip
that is a hundred times more sensitive than current devices. The researchers are now completing soil tests and will soon test their design in plants, embedding their "lab on a chip" in the stems of grape vines
, for example. They hope to mass produce the sensors
for as little as $5 each.
