Touch technology to a higher level, scholars have developed a film similar to artificial leather, which can be used as a touch interface, which is expected to make smart phones, wearable devices or computers operate better.
The University of Bristol, in cooperation with the Paris Institute of telecommunications and the Sorbonne University, has developed a silicon thin film touch interface with many layers by using biotechnology, which not only imitates the appearance of human skin, but also imitates the feeling.
These layers include a surface layer, an electrode layer with conductive wires and a skin layer. The research team said that this artificial skin touch interface can make the device “feel” the user’s grasp, including pressure and position, and can also detect itching, touching and even pinching.
Using artificial skin, the team preliminarily developed mobile phone case, computer touch panel and smart watch to actually show how to communicate information on the device through this new interface. For example, when transmitting emoticons on communication software, a strong grip will produce angry symbols, while scratching represents laughter, and a light touch will produce surprised expressions, etc.
The team pointed out that although there has been in-depth research on artificial skin in the field of robotics, it is mainly based on the purpose of safety, sensing or beautification. This research is the first time to develop a new input interface and upgrade the device, hoping to bring new possibilities for human-computer interaction.
