Written by Scott Lyon, Office of Engineering Communications; Molly Seltzer, Andlinger Center for Energy and the Environment

Researchers at Princeton and MIT have found a way to save big on power consumption for data centers while making a key electronic component much smaller.

The component, called a power converter, changes the flow of electricity to fit the needs of individual computer parts. All computers require converters to supply power, but the…

New animation tool streamlines the creation of moving pictures
Oct. 26, 2018
Written by Molly Sharlach, Office of Engineering Communications

It’s often easy to imagine balloons soaring or butterflies fluttering across a still image, but realizing this vision through computer animation is easier said than done. Now, a team of researchers has developed a new tool that makes animating such images much simpler.

The tool is designed to…

'Focused Research Teams' take on emerging opportunities in biotechnology and robotics
Oct. 22, 2018
Written by Steven Schultz, Office of Engineering Communications

In an initiative to boost collaborations on subjects too new to fit into existing departments and centers, the School of Engineering and Applied Science has created a program to fund small, cross-disciplinary groups of researchers called Focused Research Teams.

The school has named…

New tool helps users control which countries their internet traffic goes through
Aug. 2, 2018
Written by Molly Sharlach, Office of Engineering Communications

The internet gives people worldwide access to applications and services, but in many cases, internet traffic passes through a few dominant countries, according to new research from Princeton University.

Following the 2013 revelations of U.S. government surveillance, officials from several…

Implanting diamonds with flaws to provide key technology for quantum communications
July 5, 2018
Written by Catherine Zandonella, Office of the Dean for Research

Diamonds are prized for their purity, but their flaws might hold the key to a new type of highly secure communications.

Princeton University researchers are using synthetic diamonds to help create a communication network that relies on a property of subatomic particles known as their quantum state. Researchers believe such quantum…

From a spaghetti-like jumble of microfibers and water comes a promising new material
Dec. 5, 2017
When tiny strands of flexible material are forced through a syringe, they produce a highly useful material known as a hydrogel. These injectable hydrogels are similar to living tissues.
A radiant-temperature sensor for improved human comfort
Nov. 30, 2017
The Spherical Motion Average Radiant Temperature (SMART) sensor designed by Princeton Assistant Professor Forrest Meggers and his team is a simple, cost-effective device that can quickly and accurately measure the surface temperature at multiple locations in a room, creating a three-dimensional picture of the radiant heat and cooling sources.
