Researchers Develop World’s Smallest Wearable Device

“A Northwestern Engineering professor, working in conjunction with the global beauty company L’Oréal, has developed the smallest wearable device in the world. The wafer-thin, feather-light sensor can fit on a fingernail and precisely measures a person’s exposure to …

New Lithium-Rich Battery Could Last Much Longer

“On paper, it doesn’t seem like Christopher Wolverton’s super lithium-rich battery should work. For one, the novel battery uses iron, an inexpensive metal that has notoriously failed in batteries. And in another difficult feat, the battery leverages oxygen …

In historic observation, astronomers detect colliding neutron stars for the first time

” An international research collaboration, including four Northwestern University astronomers, is the first to detect the spectacular collision of two neutron stars using both gravitational waves and light. The discovery ushers in an exciting new era in astronomy — multi-messenger astronomy with …

A new way to print electrical circuits

“Within 15 minutes of meeting Mark Hersam, PhD, a renowned nanotechnology expert and professor of materials science and engineering at Northwestern University, Ethan Secor knew he wanted to work with him. Secor, a fifth year materials science and engineering PhD …

How Machine Learning Is Helping Neuroscientists Crack Our Neural Code

“Whenever you move your hand or finger or eyeball, the brain sends a signal to the relevant muscles containing the information that makes this movement possible. This information is encoded in a special way that allows it to be transmitted …

Making A.I. Systems that See the World as Humans Do

“A Northwestern University team developed a new computational model that performs at human levels on a standard intelligence test. This work is an important step toward making artificial intelligence systems that see and understand the world as humans do. “The …

This tiny electronic device applied to the skin can pick up heart and speech sounds

“Researchers from the University of Colorado Boulder and Northwestern University have developed a tiny, soft, wearable acoustic sensor that measures vibrations in the human body and can be used to monitor human heart health and recognize spoken words. The stretchable …

A New Way to Print 3-D Metals and Alloys

“A team of Northwestern Engineers has created a new way to print three-dimensional metallic objects using rust and metal powders. While current methods rely on vast metal powder beds and expensive lasers or electron beams, Northwestern’s new technique uses …

Printing 3-D graphene structures for tissue engineering

“Ever since single-layer graphene burst onto the science scene in 2004, the possibilities for the promising material have seemed nearly endless. With its high electrical conductivity, ability to store energy, and ultra-strong and lightweight structure, graphene has potential for many …
