There is an extensive amount of science break-through and amazing technology being discovered and researched on a daily basis; but unless that technology has a purpose, it will never surpass the research stage. Wireless power has been pushed aside in the past by researchers due to the fact that there was not a large market for a system like this. Within the past 20 years, portable electronics – i.e. mP3 players, PDAs, cell phones, digital cameras, video game systems, laptops – have become household items. With the amount of portable electronics that are being frequently used, batteries that are used are either quickly disposed of or need to be recharged often.
"Every single person in the world can relate to the problem of running out of batteries or having wires everywhere …The market is so potentially huge that numbers become meaningless." Eric Giler CEO, WiTricity
Wireless power has multiple applications on many different range levels. Anywhere from being able to charge your cell phone by placing it down on your desk to creating smaller, more eco-friendly, inexpensive electronics that don’t require a mandatory battery power source. The three most predominant examples of this technology are WiPower®, WiTricity©, and WHDI.
WiPower is an American company that helps inventors, researchers, and developers create new revolutionary products that use their near-field power transfer systems. The system itself is a straightforward power system with a standard “pad” style transmitter and receiver that uses inductive coupling to transfer power.
The system is limited to very short range power cycling, but this con is overshadowed by the numerous advantages to the sy...

This technology has already started to be incorporated into consumer electronics. While working with electronics manufacturer Haier, WiTricity demonstrated their product at the 2010 Consumer Electronics Show by powering a 32” LCD flat screen television without any type of cables or wires. Microchip manufacturer Intel has also publicly demonstrated this technology. In 2008, Intel displayed a unit that transferred 60 watts over two feet that was 75% efficient, according to an article by ExtremeTech. Soljacic’s research partners were able to power a 1000 watt klieg light from across the room during the Nikkei electronics conference during October 2009 in Tokyo. The WiTricity system has been documented to distribute up to 3000 watts at the moment; which is enough to fully charge an electric car.
This paper propose an adequate approach of charging and recharging Smartphone batteries by Converting Power to Data and transmitted through a Wi-Fi ( Radio Wave) connectivity, also interconnect with Power consumption application that will automate and asynchrous power consumptions . The outcome of this research is recharge Smartphone batteries whenever Wi-Fi connectivity is available and accessible. And not to worry
Rechargeable battery evolution accelerated as the world transitioned to instruments enabled by silicon microchip technology from those of bulky electrical components. Mobile devices were designed to be powered by lightweight energy storage systems. The development of batteries for this rapidly evolving market was challenging:
In this recent century, there is ease into taking our technology as something for granted. After all, technology has opened up our abilities to instantly connect to the other side of the world, instantly retrieve information from the Internet, and instantly listen to digital content if desired. However, while a cell phone, laptop, and iPod has many differences from one another, all of those three devices share one item in common at the very least and that is a Lithium-Ion Battery.
Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects. The tags contain electronically stored information. Some tags are powered by and read at short ranges (a few meters) via magnetic fields (electromagnetic induction), and then act as a passive transponder to emit microwaves or UHF radio waves (i.e., electromagnetic radiation at high frequencies). Others use a local power source such as a battery, and may operate at hundreds of meters. Unlike a bar code, the tag does not necessarily need to be within line of sight of the reader, and may be embedded in the tracked object.
One new alternative energy source that is not getting as much recognition as it should is piezoelectricity. The concept behind piezoelectricity will be examined at a greater length later on in this report. Basically the main concept behind piezoelectricity is compressing a piezo ceramic which will in turn produce a static voltage which we could
This begged the question for the “Mad scientist”. How can the world supply itself with electricity without giant power cords, so Nikola started experimenting. He came up with the hypothesis that he could use 2 metal rods.
There are companies that are crafting photovoltaic material into jackets, trousers, watches, caps and more. When one wears the attire, he or she is instantly transformed into a walking power source. The attire collects and stores energy and then avails it to the wearer or anyone else the wearer might want to share with. It is an incredible advancement that has implications beyond the charging of mobile devices. Potentially, every human can add his or her energy to the grid. It is an advancement that goes one more step towards making every human responsible for his or her energy collection. With the technology getting better and better, the potential is truly

As shown in Figure X below, the ratio between module cost to non-module (BOS) cost is about to 3:2. The anticipated system cost reduction until 2020 will be significant, approximately by half, due to economies of scale from improved module and non-module manufacturing technologies. The reduction then after would be slower as the percentage of soft cost over total system cost increases in proportion.

A wireless sensor network (WSN) consists of distributed sensors to monitor environmental conditions such as temperature, sound, vibration, pressure, motion or detect dimensions, to pass their data through the network to a base station for processing. Advantages of WSN over a wired system considered in elimination of wiring cost, sensors can be installed in harsh environments. Each sensor node is a combination of Radio transceiver with an internal antenna or connection to an external antenna micro-controller, electronic circuit for interfacing with the sensors, energy source, usually a battery or an embedded form of energy harvesting. Drawback of using sensors is having limited power to consume, a memory that is capable of performing limited computations, in addition to probability of communication failures between nodes.

The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society. Wireless technology came from the basic just cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with forever revitalizing technology.
There are two main types of RFID tags: active and passive. The difference between these two types lies within how and when they transmit their stored information. An active RFID tag is connected to a power source, ge...
