Battery has always been a biggest issue no matter how fast or smart our devices are. While buying any electronic device or gadget like laptops, smartphones, or any other gadget, the first and foremost specification we look for is the battery backup instead of processor or camera quality. The problem of battery backup seems to be a big and persistent problem and it doesn’t seem to get any better.
Imagine, if you could eliminate battery completely? Yes, electrical engineers from Washington University has developed a gadget that will not require any battery or any external power source to keep it working. Confused? Well those gadgets work with the help of radio waves.
You must be wondering if you have to keep your radio on the whole day to keep this device charged. Right? Well the answer to this is no. This device draws radio waves from air and converts them into electricity.
WISP (Wireless Identification and Sensing Platform) is a device that is a computing chip and combination sensor. It uses Radio Frequency Identification reader to draw radio waves and convert them to electricity.
WISP is designed to run sensors and transmit data and not to compete with chips on smartphone and computers. They need low maintenance in comparison to other chips used today.
Creation of Winsent interface would allow wireless programming of WISP making is more usable and easy. A team at Delft University of Technology is working on it.
WISP now requires cables that nullify the advantages of not using a battery. Hence, Winsent will allow WISP to program it wirelessly. The vision is to deploy battery-less device which will host wirelessly re-programmable software interface, everywhere.
