Scientists from Dartmouth College together with Microsoft have developed a method for recognizing contact objects to create interactive tissues.
The authors named the new technology Capacitivo and have already found its application, as a tablecloth, which can create their own recipes.
Over the past decade, several attempts were made to create flexible personal electronics that could be used for “smart” clothes. Scientists from Dartmouth College decided to switch their attention to items that require a thicker fabric, such as furniture. The main idea was that the surfaces of objects could “understand” what is on them. According to the authors, such a function of household items will greatly enhance the capabilities of a “smart” home.
For example, a tablecloth made of such a fabric could transmit information to the device connected with it (phone, computer) and offer various dishes that can be prepared using the products placed on it.
The fabric is a grid of electrodes attached to a textile substrate. Built-in sensors study the electrical capacity of the object and then transmit this data to the device.
The researchers have already conducted the first experiments with Capacitivo as a tablecloth. The scientists placed fruit on the tissues and the system analyzed them and displayed the name of the fruit on the computer screen. After several tests, the researchers found that the system was 94.5% accurate. And in the case of liquids, it was 96% accurate.
