MOBILE PHONE BASED CHEMICAL SENSORS1Sensors are basically an “electronic component”, “module” or “subsystem” that aremainly used for detecting the changes or some event that are taking place in the environment.After detecting the changes, it sends the information to some other electronic device for thepurpose of monitoring, storing and detecting. Use of sensors can be seen in the gadgets that arebeing used in a daily basis. Not only on the daily items that are used but sensors also help indetecting the “temperature”, “pressure” and also to measure something. This essay is going todiscuss about the use of mobile technology in the chemical sensors. By the use of mobile phonesfor the purpose of sensing chemicals has greatly helped in the advancement of the todays world.Chemical sensors(Edmonds, 2013) are the devices used for collecting information regarding thecompositions of the chemical present in the environment. The information that is provided is themeasurement of the chemical concertation in the environment and is also used for identificationof the chemical.The use of smartphones for the detection of harmful chemicals was started by NASA.They wanted to use the smartphones as a chemical sensor. By inventing one such device will notonly help in creating of more develop type of smartphone based chemical sensor(Li et al.,2012).One of the scientist of “NASA Ames research centre” “Jing Li” had created a sensor that wasresponding to various types of chemicals present in the gases and the environment. Theemployers mainly aimed at working with the iPhone. They made a chip that is of the size of apost stamp which helped in converting an iPhone into an important chemical detector. Theresearchers not only aimed at detecting the chemical by their name but also to detect them bytheir concentration, temperature and humidity(Wilson & Atkinson, 2014). They also wanted toshow any location of the chemical events that are taking place by the use of the GPS on theiPhone.

MOBILE PHONE BASED CHEMICAL SENSORS2One example of a mobile based chemical sensor is the “electronic nose” this wasdesigned by NASA for the purpose of detecting and identifying the molecules of the liquids andthe different types of gases. But later with some more advancement in the technology they madethe device capable of detecting the chemicals and identify the compositions or molecules presentin the chemical. It helped a lot in the process of “Mechanical advancement”, “detection of anykind of leaks in the fuel tanks or toxins used in the industries”, for the quick responding and easyselection”, “monitoring of the concentration of the vapour” (Sberveglieri et al., 2012). Besidesbeing small in size it uses the wireless technology thereby helping a lot in the detection of thechemicals and their compositions. They have combined a mobile with a Nano sensor for thepurpose of detecting the presence of a certain chemical and to measure the concentration whichis then transmitted to the server for the further processing (Brudzewski, Osowski & Pawlowski,2012). The sensitivity of this device is very high with the fast response and by the use of verylow amount of energy.Tiny silicon chips that acts like a nose can help in detecting the dangerous chemicalspresent in the environment. And by embedding the chips in the mobile phones can greatly help inthe detection of the location of the gas and to measure the level of toxicity of the gas(Lee et al.,2012). It can also help in the detection of the any kinds of leak if any case e of deliberatereleasing of toxins take place. A small company by taking help from the “Rhevision Inc.” hascompleted the 1st phase of this project and they are working on a prototype that can help inlinking this sensor with the mobile phones. In another case it has been seen that a very “ultra-lowcost paper” has been used for the purpose of detecting(Misiakos et al., 2014). A demonstrationwas done so as to show the possibility of initiating a “luminescent emission” electrochemicallyby the use of the output of audio as the function generator. The camera used in phones can also
