Chemical Sensor That Runs Without Battery

A chemical sensor, the latest in the line of advanced chemical sensors, is claimed to run without battery, under the variable conditions, making the detection of the concentration of various chemicals much cheaper and easier.

This was confirmed by Radislav Potyrailoat, a scientist at GE Global Research. He also headed the multidisciplinary wireless sensing development team, comprising polymer scientists, analytical chemists etc, which developed the sensor system.

“Without the need for batteries, we can make sensors that are much smaller in size and at substantially reduced costs. Because of that, he said. They also can be made for one-time use.”

This product, a testing and measuring equipment, is a brainchild of GE Global Research. Only last month, the researchers, engaged to the development of technological aspects, came up with this fascinating innovation.

There are great similarities of mechanism between any conventional radio-frequency-identification tag(RFID tag) and this innovative radio-frequency-identification sensor. However, the prominent difference between them is that the RFID sensor has a coating of chemically or biologically sensitive film.

This ultra sensitive film helps in the detection and measurement of various chemicals. It detects chemicals with equal precision whether in different mixtures or in all variable conditions.

As a matter of fact, this sensor is helpful in the detection of trace concentration of toxic gases such as toxic industrial chemicals. The same can be done with all volatile organic compounds and chemicals in liquids.

Then how this chemical sensor works without batteries? It has got a sensor reader for this purpose which provides it the required energy. The radio reader does so by activating the RFID chip and a sensor antenna.

Main Feature :

The unique selectivity is being regarded as the sensor's best feature. This selectivity helps to assess things better as it minimizes or removes completely the chances of inviting faults and flaws. The accuracy in the detection chemicals helps to come up with good products. It detects contamination in water and food, concentration of toxic elements etc of any amount. This invention is going to raise the standard of the services in the fields like food packaging, water supply etc and will help to curb air pollution.
