Novel 3D Printing method embeds sensing capabilities within Robotic Actuators

Soft robots that can sense touch, pressure, movement and temperature. Inspired by our bodies’ sensory capabilities, researchers have developed a platform for creating soft robots with embedded sensors that can sense movement, pressure, touch, and even temperature. Researchers at Harvard University have built soft robots inspired by nature that can crawl, swim, grasp delicate objects and even assist a beating heart, but none of these devices has been able to sense and respond to the world around them.

Inspired by our bodies’ sensory capabilities, researchers at the Harvard John A...

Tissue implants customized to a patient could soon be printed using a new type of 3D-printer under development by Nanyang Technological University, Singapore (NTU Singapore) and a Singapore-based 3D printing start-up focused on healthcare. This new printer can print the supporting structure layer by layer and insert living cells to form a live tissue that could aid in regeneration of particular tissues or organs. The industry research tie-up is one of the many partnerships made possible by the National Additive Manufacturing Innovation Cluster, also known as NAMIC.

Since the formation of NAMIC by the National Research Foundation (NRF) Singapore and SPRING Singap...

A recent study from Uppsala University shows how smartphones can be used to make movies of living cells, without the need for expensive equipment. The study is published in the open access journal PLOS ONE, making it possible for laboratories around the world to do the same thing.

Live imaging of cells is a very powerful tool for the study of cells, to learn about how cells respond to different treatments such as drugs or toxins. However, microscopes and equipment for live imaging are often very expensive.

In the present study, old standard inverted microscopes that are very abundant at Universities and hospitals were upgraded to high quality live imaging stations using a ...

Researchers at ETH Zurich have developed a lattice structure capable of absorbing a wide range of vibrations while also being useful as a load-bearing component – eg, in propellers, rotors and rockets. It can absorb vibrations in the audible range, which are the most undesirable in engineering applications. Vibrations from the propellers or rotors in propeller aircraft and helicopters can make the flight bumpy and loud, and also lead to increased fatigue damage of the aircraft and its components. A new 3D lattice structure developed by ETH scientists could now expand the possibilities of vibration absorption.
