NailO involves multilayered miniaturized hardware that wirelessly transmits knowledge, via Bluetooth, to a mobile device or computer.
That means you are walking around with electrical phenomenon sensors, battery and 3 separate chips -- a microcontroller, a Bluetooth radio chip and a capacitive-sensing chip -- packed onto your nail. The NailO uses a multi-purpose chip that mixes a wireless radio, a micro-controller, and electrical phenomenon sensors, in conjunction with a zero.5mm battery. once worn on a person’s fingernail, users merely swipe and faucet on the sticker to regulate any paired device, permitting them to navigate PCs, smartphones, and tablets from a distance.
