Researchers at Concordia have developed a novel method of 3D printing that uses acoustic holograms. And they say it’s quicker than existing methods and capable of making more complex objects. The process, called holographic direct sound printing (HDSP).
Now, by embedding the technique in acoustic holograms that contain cross-sectional images of a particular design, polymerization occurs much more quickly. It can create objects simultaneously rather than voxel-by-voxel.

Fortunately, an international team led by researchers at Korea University Graduate School of Converging Science and Technology (KU-KIST) developed conductor materials that it claims are stretchable, self-healing, and bio-compatible. The biodegradable conductor offers a new approach to patient monitoring and delivering treatments directly to the tissues and organs where they are needed.
For example, a smart patch made of these materials could measure motion, temperature, and other biological data. The material could also be used to create sensor patches that can be implanted inside the body, and even mounted on the surface of internal organs. The bio-compatible materials can be designed to degrade after a period, eliminating the need for an invasive procedure to remove the sensor later.
