3D printing is used to come up with three dimensional objects and is a form of additive manufacturing. It is now easier and more affordable to come up with a prototype using the 3D technology. Before these technologies were introduced, it used to take several hours, skilled labor and tools to create a prototype.

One form of 3D printing technology is made up of inkjet printing systems. Fine powder layers made of resins, corn starch or plaster is bonded selectively on adhesives produced by the inkjet print heads. This kind of technology makes it possible to print a full color prototype and is considered to be one of the fastest methods. Read the rest of this entry »

The cornea is the clear protective layer covering the eye. Injuries and diseases affecting the cornea might lead to adverse eye problems like blurred visions. The cornea is responsible for filtering out ultraviolet rays that comes from the sun. However, with the advancement in medical technologies and the constant efforts of scientists through research, corneal diseases can be treated. The artificial corneal implants are the most recent of the treatments.

Artificial corneal implants proved to be beneficial because: it caters for the huge number of people who are waiting for corneal transplants and operations for instance Europe has a waiting list of over 40000 people and a worldwide list of 10 million. They are also biocompatible ensuring that there are no complications when in contact with the eye surface. In cases where traditional corneal transplants (also referred as corneal grafts) have failed to work, artificial cornea can be used. The risk of getting diseases from donors is also reduced. It prevents astigmatism and enhances rapid visual recovery.  Additionally, they are useful to patients who have not qualified to get living cornea donors. Read the rest of this entry »

Brain scan and mind reading of the part of the brain responsible for memory have been used to detect a person’s location in the virtual environment. This enables the location of individuals as they navigate through the virtual rooms. These are used to discern what someone was doing, where they are or were and where they are planning to go. This shows that detailed mind reading will be possible with the advancing technology and research.

The hippocampus underpins the ability of a person’s mind to navigate, form, recollect memories and imagine future experiences. The mind reading and scanning is done by using multivariate pattern classification and high resolution functional MRI to decode activities across the population of neurons in the human medial temporal lobe while the participants navigate in a virtual reality environment. The position of an individual can be predicted accurately even when the visual input and task are held constant. Reading precise locations or other types of memory is difficult because fMRI (functional magnetic resonance imaging) resolves the activity of thousands of neurons at a time.

In this era when technology continues to get advanced and better, it may pleasantly surprise many to note that machines are getting closer to humans and they are performing duties that no one hitherto would be possible. In other words, machines and gadgets are being invented that can imitate the human functioning, for example in the human brain, eyes and so forth.

But perhaps one of the latest inventions, that is a clear manifestation of humans getting even closer to humans, is a machine that has been made and which can imitate the human voice. The machine was invented as part of a completion, for the Artificial Conversational Entities, known as the ACE. Several machines that could imitate the human voice were entered for the competition and the winner was really awesome. During the competition, judges selected some of the five best machines and competed for five minutes, to get the best. This comprised if a five minute kind of interrogation, where there were unrestricted conversations with the machines, which tried to pass of as human beings. So real did these machines sound, that one would not tell whether one was a machine, or a human being. Read the rest of this entry »

With the current talk about global warming, and the impact of carbon emissions on our planet, focus is now shifting to green energy, and wind electricity has reigned supreme in this regard. People, organizations, and even governments are investing heavily in coming up with wind turbines to generate the much needed electricity. However, traditionally wind energy has been associated with huge installation costs, expensive turbines, and so forth. In this regard, researchers have come up with the less expensive Vibro wind set up, which uses less space, is not as expensive, and produces much electricity.

These Vibro wind panels will work like the solar panels do, where they will be fitted on top of buildings, where they will not only generate electricity, but will also convert even minor wind breezes. Unlike windmills and turbines that need plenty of space for them to be installed, the Vibro wind panels will herald a new dawn, where smaller and equally effective wind set ups will be used. It is worth noting that this project is being done in conjunction with engineers and architects, to ensure that it does not flop. This is also meant to ensure that the mechanical energy is easily converted to electrical energy. Conversion of the mechanical energy to electrical energy is being made possible by using a piezoelectric transducer. Read the rest of this entry »

Electronics is a very wide stream. The subject is very vast in itself. The electronics is the main source of almost everything that is happening today. The whole working of the items is dependent mainly on the electronics base. In our daily live we can see uncountable examples of the number of electronics that are being used around us. From our environment itself we can see that how the electronics can find its use in so many departments of work.

The human beings are slowly becoming addicted to the use of the electronics in their lives. They have become almost dependant on the machines for their work. For example the computer is the most commonly used machine which is the best illustration of the use of electronics in our lives. The people have started being dependent on these machines at a large extent. All the work that was earlier known to be done by the people is now seen as to be done by the various machines and also the computer. Such is the help provided by the electronics to the people in their lives. Read the rest of this entry »

Robotics has been one of the most attractive feature and study that the scientists are working upon these days. They have come up with various robots of different functionalities. They try their best to evolve and make such a robot that serves their purpose in the best possible way. A robot is basically nothing but a machine which is programmed by the programmer who develops it in a way that it performs the desired function for which it is made up.

It is given a very similar experience like a human being so that it looks even more real. It is programmed in such a way that it also performs certain actions like the humans and can also walk. A general definition of the robotics states that it should at least perform the data processing and should be able to move objects. Walking robots are the most wanted ones these days.

The lab is a diverse area. There are many instruments set up in a laboratory. There is a lot of variation in the type of these instruments and technologies in a lab that we can see today. If we go thirty years back in time then we will come to see that the technologies that exist in the labs today are far much better than those that existed previously. It can hence be seen that with the lapse of time a lot of advancements are made in the science field which has lead to the improvement in the technologies that are used in the labs. A lab basically needs the best of instruments so that all the purposes and experiments that need to be carried out are done very efficiently and very easily. The types of instruments that are available in the labs today are the most developed and latest ones. It was not even imaginable to the people few years back that such instruments could also exist. But the answer is here as we can see that yes we have achieved the best ones in the recent years. The ones that we have today are much more easy to use and are far too much sophisticated than the ones that were used long time back.

Nano devices have become very popular and famous these days. All this is due to the advancements being made in the field of science and technology. Nano devices are being made that are being powered by motion also. This is the latest advancement that has been seen lately. It has also made its use in the field of electricity. It has been seen that when 20 thousand nanowires were made to be crammed up so as to make a three centimeter square the very first power device can be created which will be powered on its own by the help of the piezoelectric materials and items. This was first done by the company known by the name of Georgia Tech. This material which is said to be piezoelectric has its own functionality. When it is pushed or pulled there is some sort of mild electric form charge generated. Hence we can see how it works. With more advancements it can also be seen that these piezoelectric nano wires can also be woven properly in form of any simple cotton shirt  or in any person’s shoe which would charge the battery of a cell phone by just simply walking. This is the most important and attractive feature of this which is also responsible for the popularity it has gained.
