By touching your fingernails, you can freely control smart terminals such as mobile phones and tablets. The latest invention of a wearable sensor makes this cool idea a reality.
According to the official website of the Institute of Electrical and Electronics Engineers (IEEE), the MIT Media Lab invented the device called "NailO", which uses a capacitive sensor to achieve touch operation - with the Apple mobile phone touch screen The sensors used are the same. In addition, it includes a battery, a microcontroller, a sensor controller, and a Bluetooth radio chip. Of course, all of this is gathered on a fingernail-sized device. Researchers published the results of this research at the American Computer Society Human-Computer Interaction Conference on the 21st.
“NailO†helps people to freely control smart devices when their hands are occupied. For example, pick up a phone while cooking, or browse the web while ironing. The device can also make mobile phones or other wearable devices more powerful by extending the input. For example, by directly operating on the fingernail, the keyboard of the mobile phone can be switched between letters, spaces, expressions and the like.
It is worth mentioning that the appearance of “NailO†is very inconspicuous, which means that people can interact with smart devices through “I don’t know, ghostsâ€. Imagine "NailO" might be a big help when you are in a meeting and want to quickly reply to an important text message without wanting to get noticed.
"NailO" has an average power consumption of 4.86 mA and can continuously transmit data for at least two hours. Researchers say this is the worst case because they have not optimized the battery of the device. In addition, people can let it stand by when they don't use "NailO", which can greatly extend the battery life. Researchers say that in the future, this device may use tiny batteries that are only half a millimeter thick, and will concentrate all electronic components on one microchip to become more compact.
The device is inspired by the colorful nail stickers that are favored by Asian women. Researchers say that you can consider designing a replaceable "skin" for the commercial version of "NailO" so that users can change the look of their dress based on their own dress.
