In this age of smartphones and tablets, touch-sensitive surfaces are everywhere. They are also vulnerable and can easily be damaged if left unprotected. Not only that, people also think that one day, they can also install full-body sensors on the surface of robots, airplanes, cars or other machines, so that their surface also becomes an operable touch screen. However, how to protect these sensors becomes a big problem.

It is understood that when the beetles are poked or stimulated by external pressure, they will change their appearance color. Recently, researchers at the Massachusetts Institute of Technology (MIT) were inspired by the characteristics of the beetle to invent a "skin" material that can protect sensors.

MIT electrical engineering and computer science researchers introduced their new design in the latest issue of Advanced Materials Technology. In order to make their ingenious design, the team turned their attention to 3D printing technology. They used a custom 3D printer called MultiFab to make this T-shaped gadget, which has a small circular object on it, and when the T-shaped crossbar is stretched, its color changes. MultiFab can print almost everything from ultra-thin, sensor-filled plastic housings to storage and curing semiconductors.

It is understood that the skin mimics the principle of the Beatles, and produces different colors according to different pressing forces, so that different sensing information can be generated according to different pressing forces. While protecting the internal sensor originals, it will not affect the normal operation of the sensor.

The person in charge of the research project said that in nature, the network connected between the sensor and the communicator is called the sensorimotor path. Researchers say they are trying to see if we can replicate sensorimotor pathways within 3D printed objects. So, they considered the simplest creature that could be found.

For now, this design is only a preliminary idea presented by researchers. However, they will plan to continue developing the technology. The development team also said that the design is not just a sensor used to protect the touch screen. It can also fold the skin into complex shapes through 3D printing. Therefore, for some abnormal structure sensors, it can also play a protective role.
