Now a days the wireless technologies are more in use and are widely evolving. Some of the technologies now in use are Wi-Fi, Wi-max, Zigbee, Bluetooth. Out of which Bluetooth is most popular. These technologies are widely used to connect the large devices like mobile phones or personal computers. No existing wireless technologies will connect with small button cell battery devices so effectively. So Nokia introduced the new radio technology called Wibree in 2006.

• Button cell batteries are small, thin energy cells that are commonly used in watches, hearing aids, and other electronic devices.

•The button cell battery has become a primary power source for many portable electronic devices such as radios, hearing aids, watches, calculators. • Button-type batteries, because of their compact size, permit electronic devices to be built which themselves are very small or compact.
