SAN FRANCISCO, USA: Norwegian tech company One2Touch has unveiled a completely battery-less portable keypad for Android smartphones at the WIMA USA Conference in San Francisco.

The fully working concept has no battery, and harvests just a few milliwatts of power from the smartphone while in use. It draws zero power from the phone when not in use.

The One2Touch battery-less keypad is engineered to require only miniscule amounts of power from the smartphone it is paired with.

Connecting via Near Field Communication (NFC), the portable, completely wireless keypad draws power from the NFC field of the smartphone, behaving similarly to a passive NFC tag.

One2Touch's testing revealed that for a typical use case of composing a message or email, a smartphone screen used hundreds of milliwatts of power. By comparison, the One2Touch battery-less keyboard device used less than five milliwatts during the same use case.

Patents are pending in the US and China for the proprietary technology behind the device.
