Programmable materials that detect their own movement

Programmable materials that detect their own movement

The Massachusetts Institute of Technology has created 3D printer-printed materials that can detect their own movements. Using air-filled channels, sensors can detect pressure changes and determine structural deformation.

Researchers from the Computer Science and Artificial Intelligence Laboratory have developed "engineering materials" that can detect their own deformations. These materials are 3D print structures that are considered programmable because it is only a slight change in their geometry to change certain properties, such as rigidity or strength.

In their work published in the journal , researchers describe the 3D seals of DLP using photopolymer resin that hardens when in contact with light. They were able to create a complex design in which all the elements are hollow. When it starts to deform, the air comes out and is measured by the pressure sensor.

Gap in the field of soft robotics

They used this technique to create a soft robotic platform with four degrees of freedom, with four servometers and 12 sensors, and they controlled the robot and recorded the sensor data for 18 hours using the motion sensor as a reference. Using artificial intelligence, they were able to analyze the data using a neural network and to create a model that could detect the motion of the soft robot using only the pressure sensor data.

Researchers hope that their method will lead to the development of soft robotics, providing robots with accurate pre-supplicative sensors built directly into their structure; it can even be used to create connected clothing or accessories that can determine the owner ' s movements and its interaction with the environment.
