14- Wireless Transmission

Ever thought of the wireless power transfer over long distance? And the wireless power transfer with no plugs and nothing to do with wires! Just as simple as transmitting and receiving. Sounds great!

Wireless power transfer (WPT), wireless power transmission, wireless energy transmission, or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link.

In a wireless power transmission system, a transmitter device that is  driven by electric power from a power source, generates a time-varying electromagnetic field, which is capable of transporting power to a receiver device through open space, which extracts power from this field and supplies it to an electrical load. 

The latest example of wireless power transfer is wireless charging of smart phones, earphones, etc. The technology is rapidly developing and will take greater stand in the later years.

An important issue associated with all wireless power systems is limiting the exposure of people and other living things to potentially injurious electromagnetic fields. But wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible.

The main advantage of this technology is that wireless power allows you to completely seal your device. Whether you’re looking to get rid of a power port, remove something you don’t want in the system, or advance your product from water-resistant to waterproof, wireless power could be your perfect solution.

Another key benefit to wireless power is the highly expandable power range it offers. Wireless power offers a multitude of real-world applications with anywhere from 0 to over 200W of power transfer. The level of efficiency is thus very high.

The last major benefit of wireless power is increased product life. By eliminating the physical limitations of connectors (like mating cycles, corrosion on contact points, and the like), wireless power offers a more robust product to design manufacturers.

19. Impact of COVID-19 on Technology and Cyber Security.

The world is experiencing the economic breakdown and is trying to cope up with basic amenities required for the people to survive. The COVID-19 has even challenged the economy and is affecting all the sectors. Lockdown has proved to be a solution to stop the virus transmission but is affecting the industry. But what are its impacts on technology?  The effects of COVID-19 are having a significant impact on the technology sector, affecting raw materials supply, disrupting the electronics value chain, and causing an inflationary risk on products. More positively, the disruption has caused an acceleration of remote working, and a rapid focus on evaluating and de-risking the end-to-end value chain. In addition, potential carbon emission reductions could result in renewed focus on sustainability practices. This article considers the shifting landscape across a number of areas. The main impact will be on the cybersecurity and even on supply chain. As due to this pandemic s...

17- QR code vs SnapTag

Are you tired of seeing those ugly black and white square blots everywhere you look? Well now there is a solution; SnapTags.  SnapTags are raising the bar for interactive communication. SnapTags work like QR codes but give you much more. Instead of using a 2-D barcode, you now are able to use your very own logo that’s much more visually appealing to the consumer. This branding tool is extremely powerful for initiating consumer engagement at which the consumer is likely triggered by an emotional response. QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode. A barcode is a machine-readable optical label that contains information about the item to which it is attached. SnapTag provides trackable, device-aware, fully programmable QR codes that can deliver the best experience in any situation, for everyone. How is the look of snaptag? Well, here it is! Sample model This look is the basic snaptag model of this blog. This tag can be...

15- 3D printer

We are all familiar with the 2D printer i.e the black and white or colour printer. The photocopy of any document is printed with the printer as per the input image that was given to it. The later world expected the things to be experienced in the actual dimensional view and this led to the invention of the 3D printer. Now, what actually is a 3D printer? Making the desired objects of any dimensions as per the actual image that was given to the input is called as the 3D printer. The image sends the information like the height, width, depth, etc to the printer through the sensors or even manual inputs can be given. The obtained information is then processed, brought together to make a digital image and hence, the printing starts. The material used here varies as per the requirements. Some materials such as liquid molecules or powder grains being fused together and the desired shape are given. The printed objects are then made to cool and acquire the firm shape. The resulting object ...
