Indian Innovation for Charging Phones

We Indians are usually not knows for Innovation, but the culture is changing. Or should I say the mindset of people going from I need a good job to I need to start something of my own is coming in. And the basis of this seems to be innovation. People are beginning to think on why there is the need to develop stuff for other companies when you can make it as your own. In a case where this concept is getting more obvious, I would like to showcase some scenarios where Indian Innovators have come up with solutions for the country made by people in the country, which of course is a recipe for success.

In our journey we will start with Mobile Chargers, one of the biggest woes these days when it comes to mobile phones is the fact the batteries do not last. And Batteries not lasting is a even more of an issue in developing countries as there might be no electricity to charge them back on. Well lo and behold, these innovations will help.

Nokia helping to find lost keys

Everyone has mobile phones these days, and those days are nearly gone when you would hear “I left my Mobile at home”, I think its been a while since I have heard that excuse. Well this just means that we dont really go anywhere without out mobiles, and what do we do if we cannot find it when we are about to leave the home, well we call it and there it is. However, I am sure that at times when we are looking for keys and cannot find it, someone in the room says, Give it a call and everyone laughs. Well what if that could be really possible ?

Nokia again with Self Charging Phones

[tweetmeme] A few days back I wrote about Nokia Research center working on a prototype technology that would allow cell phones to charge using the radio airwaves that so many radio  transmitters like wifi, radio and GSM use.

Nokia is a genuine game player when it comes to modernizing mobile communication. When just everything is being designed to run on alternative form of energy, it’s fitting that even the mobile phones are set on route. For this, the cellphone maker has filed a US patent application for a phone that can work continuously without requiring to be plugged into a wall socket for a recharge.

The patent is for a self charging phone, which would harvest energy from its owner’s motion. This will be possible courtesy built-in piezoelectric generators that would be placed to help generate electricity from kinetic energy. The phone will have all the heavier components, such as the radio transmitter circuit and battery, supported on a sturdy frame. The frame will be able to move along two sets of rails. Piezoelectric crystals sit on the end of each rail and generate a current whenever the cellphone is moved. So as the user walks, or otherwise moves the phone, electricity is generated to recharge the onboard battery.

A lot of people actually are these days talking about how Nokia is loosing its grip on the cellphone market and the high end innovation is no longer coming from Nokia. However, with technologies like these there seems to be a ray of hope for Nokia to walk back into the hearts of the skeptics. The fact that the iPhone and other high end phones still cost more than they do in the United States in most of the world will definitely give Nokia the time they need. What do you think ?

Nokia charging phone with thin air …

[tweetmeme] We all have had Nokia Phones at some time, and we always have loved them for their robust nature along with their ease of use. A lot of people mention that with the new technologies in the world, Nokia has sort of lost its relevance. I think on the other hand Nokia is looking at different markets than the giant that it has become, iPhone and the Phone that aspires to be the Giant, the Motorola Droid, or the Google Nexus One.

As long as technology is moving on, so is the need for more juice in the batteries of the phones. More requirement for the power means that there will be more advancements required in batteries; or charging for the batteries. What if you dont really have to charge them at all, I mean physically. Ofcourse there are ways, like kinetic energy transformation, solar energy etc. But here’s another concept; Like Nokia I have always been wondering about how much energy is in the air all around us, I am not talking about the energy of people; but more to do with energy of wireless radio systems. Be it FM transmitting radio, GSM signals, Wi-Fi Signals or terrestrial radio systems. What if we could tap into that power to enable mobile phones to pick up the charging of the batteries from there. Completely wireless, and completely practical.

I guess what needs to be worked out is how long it will take to tap this power and how long can you charge the phone with this. Well Nokia is at it again, their innovation well not really aimed at high end phones but mostly innovation like these. Nokia Research center is working on a solution that will help the cause of wireless charging.

Nokia

A new prototype charging system from the company is able to power itself on nothing more than ambient radiowaves – the weak TV, radio and mobile phone signals that permanently surround us. The power harvested is small but it is almost enough to power a mobile in standby mode indefinitely without ever needing to plug it into the mains, according to one of the researchers who developed the device at the Nokia Research Centre in Cambridge, UK. The concept is being worked upon by different fronts, old crystal radio sets and more recently modern radio frequency identification (RFID) tags, increasingly used in shipping and as antitheft devices, are powered purely by radiowaves.

The difference with Nokia’s prototype is that instead of harvesting tiny amounts of power (a few microwatts) from dedicated transmitters, Nokia claims it is able to scavenge relatively large amounts of power — around a thousand times as much — from signals coming from miles away. Individually the energy available in each of these signals is miniscule. But by harvesting radiowaves across a wide range of frequencies it all adds up. Such wireless transfer of energy was first demonstrated by Nikola Tesla in 1893, who was so taken with the idea he attempted to build an intercontinental transmission tower to send power wirelessly across the Atlantic. Nokia’s device is somewhat less ambitious and is made possible thanks to a wide-band antenna and two very simple circuits. The antenna and the receiver circuit are designed to pick up a wide range of frequencies — from 500 megahertz to 10 gigahertz — and convert the electromagnetic waves into an electrical current, while the second circuit is designed to feed this current to the battery to recharge it.

Wireless charging is not intended as a sole energy source, but rather to be used in conjunction with other energy harvesting technologies, such as handset casings embedded with solar cell materials. According to Technology Review magazine, the phone could be on the market in three to five years.

In the meantime, there are other companies who are working on similar concepts  for charging devices wirelessly using the ambient radio waves. At CES 2010, RCA introduced something even better that’s going to be available way sooner: a dongle that tops up your mobile device’s battery via WiFi signals. Notice I didn’t say that it only tops up your cell phone battery; according to RCA reps, this little fella will work with just about all of your mobile devices.

The attachment is efficient enough that it actually provides a noticeable boost to your battery, and given enough time it will charge it to the max. Other similar gizmos have provided only a weak top-up charge at best, so this is a huge improvement. And what’s even better is that the device will be available for around $40 in the summer of 2010. Soon, as long as you’re in an urban environment or around a WiFi router, worrying about your phone’s charge will be the last thing on your mind.

The future applications of the technology are exciting as well. In 2011, RCA expects to release batteries with the WiFi charging capability built right in. There’s no word yet on how much those will cost, but does it matter? The prospect of never having to plug your phone in again will probably be enough to have them flying off of the shelves.
