In day to day world the internet of things is one of the emerging technologies. Through wired and wireless medium IOT connects various object which helps the human to interact with objects in both digital as well as physical world. Due to increase of population the services are very challenging for the providers. To overcome those challenges the IOT has developed with many applications. IOT contain the sensor which connects to Bluetooth, Wi-Fi, RFID and also it covers wide area with many technologies like GSM, 3G and GPRS. The IOT devices collect many useful information from various devices and flow the data between many devices. The flow of information can be done without human-to-human or human computer interaction. Due to IOT the world will become smart so it is called as smart home, smart cities, smart building and also some applications. Many sectors are connected to RFID technologies like banking, agriculture, education, domestic appliances monitoring, Surveillances, government government -e services, traffic surveillance, meteorology and security and emergency. This devices also consist of heat, light, security system with less cost. The online capable devices 31% in 2016. It increased up to 8.4 billion in 2017. The IOT devices will be increased more than 30 billion in the year of 2020.
Glaucoma is a disease which leads to a permanent blindness to a person. Many techniques are available in medical industry to detect glaucoma. Some traditional techniques are HRT and CO them are cost effective and time consuming. These inefficiencies leads to the emergence of automatic computer aided system which can detect glaucoma in less time. Optic disc and optic cup smashes an important role in glaucoma detection. This gives an study of various techniques that are used in glaucoma detection using automated systems.
Nanorobotics is one of the emerging and advanced technology in various field. The scientist throughout the world involves in research and development of nanorobots. The size of nanorobots is 10 it is opposed to microrobotics. It is composed of many nano components. The range of device is 0.1 micrometer.It plays main role in medical industry as well as space industry. Nano medicine is developed using nanorobots. The nanorobots is highly durable. The largest contribution is given by IT (Information Technology) and sensor Technology for the development of Nano Technology. Nanorobots different from macro robots due to some scale and material, even there are some similarities and control techniques. The nanorobots self-replication because it replace worn producing the copies of themselves. Nanorobots helps to treat some diseases like removal of kidney stone, diagnose and treat the cancer cells in human body, eliminate the defected parts in DNA, cerebral Aneurysm and also some other treatments and save the life of human. Robotic devices are used to help the patient in hospital rooms, complex surgery can also be performed using the robot, laboratory test can also be performed, some missing limbs can be replaced, help in rehabilitation after stroke and also to diagnose some diseases. Nanorobots are nano devices used for protecting and maintaining the human body against pathogens. Nanorobotics can be named as nanoids, nonomites, nanites or nanorobots can be used to describe hypothetical devices. This paper helps to review the working of nanorobots in medical field and also it gives the detailed explanation of its application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
