Engineers connect health wearables and implants using the body as the network

Using the human body to transmit signals, Georgia Tech engineers have created a wireless networking system that allows tiny implantable sensors and actuators to communicate with each other and with wearable devices. Their system means devices can work together like never before, sensing in one part of the body and triggering a therapeutic response elsewhereβ€”perhaps releasing medicine or stimulating a nerve.

Unlocking sulfur's third electron boosts lithium-sulfur battery voltage and capacity

While lithium-ion batteries (LIBs) remain the most widely used rechargeable batteries worldwide, energy engineers have been testing various alternatives with different underlying chemistries. These include lithium-sulfur batteries, which store and release energy by moving lithium ions between two electrodes on opposite sides of a cell, while sulfur undergoes reactions in the cathode (i.e., positive electrode).

Teaching radar to read motion in traffic scenes

Autonomous vehicles and robots need to understand not only what is around them, but how objects and people are moving. A cyclist crossing the road, a car slowing down, a pedestrian stepping off the curb, and a parked vehicle all create different motion cues that a machine must interpret quickly and accurately.

Researchers redesign carbon fiber for multifunctional energy storage

Imagine if your car weren't powered by a conventional battery under the hood but by energy stored in its walls or even its roof? This is a future that Dr. Bhagya Dharmasiri and her colleagues at the Deakin Institute for Frontier Materials have been exploring, bringing load-bearing structures and rechargeable energy storage together to create structural battery composites.

Broadband distributed amplifier for data centers, measurement systems and sensors

Modern data centers, high-precision measurement systems and high-resolution radar sensors rely on extremely broadband amplifier chips that combine low noise with high output power. Researchers at the Fraunhofer Institute for Applied Solid State Physics IAF have developed a monolithic microwave integrated circuit (MMIC) with strong performance in these areas.

Soft surfaces offer rewritable way to guide, sort and merge droplets

Mechanical and aerospace engineering professor Anupam Pandey's research team has found that microscopic folds in soft materials can act like tiny, programmable traffic gates for liquid droplets. The folds can stop droplets, let them pass or merge them together without surface coatings or additional hardware. Remarkably, the droplets never touch the fold. They sense it from a distance and slow down, stop short or change course in response. The study is published in the Proceedings of the National Academy of Sciences.
