Wireless Electricity’s influence will have global implications on humanity. In modern times and a world that continually demands more and more mobility and accessibility, the trend of wireless technology has spread like wildfire. Progressively, it has been spreading to the field of power transfer as well. When you combine the two, power transfer and wireless: Welcome to the world of wireless power transfer. This concept of wireless power has been fantasized, flirted upon, and re-flirted upon for several decades now in hopes to create a world with self-sustaining-like, mobile, and highly personalized electronics. Advantages and disadvantages exist on both the use and nonuse of this new technology, leaving us with many issues to consider. As our society’s technological needs and wants become more mobile and accessible, so has the need and want of transferring power wirelessly. Wireless power transfer (WPT), is a way to deliver power from a source to another device without having to use wires or contacts.
There has been a definite growth in the use of portable electronic devices. This growth has led to an increased need in the market for wireless power transfer devices. Imagine living in a house where you had no need to plug any cord into an outlet to make an appliance or device work. This would be beneficial for both the electrical systems of a house as well as to the members of that household. There would be no cords to trip over. This would also eliminate single outlets being overused and fuses being blown due to the surge of power required for one outlet. On a personal note, I think it would change my life greatly not having to use a cord to plug in my laptop to finish my homework. Now that would be awesome! Would you continue ...

Parkinson’s) with excellent success. The scope of indications for deep brain stimulation is increasing and now includes a variety of movement disorders, pain syndromes, epilepsy, and also psychiatric diseases (e.g. OCD)” [Marko]. Currently, deep brain stimulators are the leading implant for patients with different diseases, and they will be able to cover a wider range of disease and disorders in the future. Deep brain stimulation involves implanting a brain pacemaker into the brain. The pacemaker, also called a pulse generator, can then stimulate parts of the brain which relieves the patient from symptoms of the disease. Deep brain stimulators use the electrode in the pacemaker to send electrical pulses to parts of the brain. These pulses stimulate cells in the brain, which reduce symptoms for diseases. Stimulating the brain does work and it has worked for thousands of patients, however, scientists are not fully certain why this technology works for the brain. The performance and understanding of deep brain stimulators will improve as more data is collected through research and existing patient records.

The outcome of this research is recharge Smartphone batteries whenever Wi-Fi connectivity is available and accessible. And not to worry
In the early 1950s, the first ever amazing invention of an external cardiac Pacemaker was developed by Dr. John Hopps. It was large (about 30 cm long, and several centimetres high and wide), the pulses were generated by vacuum tubes and the entire unit was powered by 60 Hz household current.(The Pacemaker) Hopps was an electric engineer appointed by the National Research Council of Canada in 1941 after training at the University of Manitoba as an electrical engineer. Pacemakers helped with the pumping of blood by sending electric signals but it occupied too much space. John Hopps was recognized as “The Father of Biomedical Engineering”. "The financial cost of the pacemaker was minimal" which made the pacemaker even popular and appealing as a weapon to treat problems in rhythm of the heart. (Drew)
The leading cause of death globally are Cardiovascular diseases. They are responsible for more than 17.3 million deaths per year, a figure which is projected to rise to 23.6 million by 2030. In the USA alone, around 2200 Americans die each day from these diseases which is one every 40 seconds. Cardiovascular diseases like strokes or heart attacks can be mitigated for an extent using implantable devices like heart pacemakers. As advantageous as it may sound, there are a few limitations to them too. For example, once the battery life has depleted, the device must be surgically replaced for uninterrupted regulation of the cardiac system. The average battery life of a pacemaker is about 7 years. This leads to repeated surgeries
Batteries do not power most RFID tags; these are identified as passive tags. These passive tags are dormant until they receive a signal activated by the reader [8]. In contrast, active tags have a power source, are not as common and have a larger footprint, but can be read from much longer distances [9]. RFID is bec...

The discharge current flows through the stimulating coil to generate the necessary magnetic pulse. This pulse induces current in electrically conductive regions of the human body. If the induced current is of high amplitude and duration it will stimulate neuromuscular tissue in the same way as with conventional electrical stimulation. The first commercial magnetic stimulators originated from Sheffield in 1985 [16-21]. A typical magnetic stimulator consists of a capacitor charging or discharging alternatively with the appropriate control and safety electronics. Using the charging circuitry the energy storage system (capacitor) is charged to a level which can be up to a maximum of 3000 volts (kV) depending on the device. When the device receives an input signal as a trigger, the energy stored in the capacitor is discharged into the stimulating coil. The stored energy, with the exception of the energy lost in the wiring and capacitor, is transferred to the coil and then returned to the instrument to reduce coil heating. The discharge system consists of a switch and an electronic device, either a power metal oxide semiconductor field effect transistor (MOSFET) or insulated gate bipolar transistor (IGBT) or silicon controlled rectifier (Thyristor), and is capable of switching large currents in a few microseconds. Power MOSFETs, IGBTs and Thyristor conduct current only in one direction. As indicated in Figure 1 there are two types of waveforms: monophasic or biphasic which is commonly found in magnetic stimulation

Different techniques are discussed in this review paper for dealing with different issues of designing wearable antennas. Electrical and dielectric properties of textile materials are not readily available. So, it needs to be calculated first. Detuning effect due to human body can be minimized by putting conductive layer between antenna and human tissue. Bending effect of antenna can be reduced by using EBG structure. Water absorption effect on antenna also can be minimized by choosing appropriate materials. By putting cover to antenna, we can reduce effect of physical abrasion and other environmental
Electricity and electrical components are a major part of our lives today. Our lives pretty much come to a halt if there is a power outage or if our electrical devices stop working, sometimes we even start panicking because we are so dependent on these components that we cannot afford to lose them and their importance and use only increases as time passes. We all use these electrical devices and also electricity itself but most of us do not think about the math and physics that works behind all of these things.
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.
Wearable antennas are meant to be worn on human body so that it must be light weight, low profile, flexible, un-obstructive and rugged. To fulfill this requirements, textile materials are used to make wearable antennas. Electrical and dielectric properties of these textile materials are not readily available. Unlike, antennas embedded in portable devices, wearable antennas are designed to work in the complicated body-centric environment. Antenna performance near to human body is different than antenna placed in free space. Environmental effects and water absorption also affect antenna performance.

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.
During today’s time period, technology have been evolving at an exponential rate. The BrainGate technology have advance greatly since the time it was invented. This brain computer can now be used by strapping a transmitter to the patient’s head and wired electrodes into the skull would their thought command to be delivered wirelessly as fast as a home internet connection. Arto Nurmikko, the professor who led the creation of this wireless system states “the device transmits data out of the brain at rate of 48 megabits per second (Regalado, 1, 2015)” and use only a fraction of power of what a smartphone would use. The BrainGate have not meet its full potential, even though the implant is able to transmit a large amount of data a day, it is not much compared to what the human brain can generate by performing a simple movement. According to this article, the BrainGate will never be used in actual medicine, until it is further developed and becomes for reliable; the head module is just the
