Researchers Develop Wireless Battery-free Computer Input Device


Whenever we hear the word ‘device’, we always think of some kind of electronics that need batteries or some other power source. However, it’s not always the case. Researchers from the University of Waterloo are now successful in developing an input device for a computer that doesn’t require batteries. However, that’s not even the best part!

How Does The Device Function?


The device is called as Tip-Tap. This device does not need any internal or external source of power. This is because this device uses RFID (radio frequency identification) tags. With these RFID tags, the device can sense whenever users’ fingertips touch and send out signals. Basically, the device works as an RFID antenna with two separate halves. Now, each of these halves needs to be put on different fingers. Generally, an index finger and a thumb are the most common choice. Moreover, each of the sides contains three chips.

These chips enable a two-dimensional finger input. As the fingers join together, a complete RFID antenna is available to send out signals. The antenna is able to alter the ambient or surrounding radiofrequency. This is a very small change. However, a computer is able to detect this change in frequency. Several functions and operations can then be developed to detect this change. Thus, the result is very similar to button input.

This new device now has immense end-use applications. One of the most prominent ones is for surgeons. The majority of surgeons use computers during surgeries. However, they cannot actually touch them. However, by integrating Tip-Tap in their surgical gloves, researchers could empower surgeons to remotely control a computer. Moreover, this also considerably saves time as it helps avoid constant changing of gloves and sterilization during the surgery. There are sever other application areas where Tip-Tap can come in handy. Industries, manufacturing plants, and factories among others can become huge end-user applications.
