A new handy sensor can enhance food safety

A new system for testing food safety developed by an interdisciplinary research team, led by Dr Roy Vellaisamy, Associate Professor in the Department of Materials Science and Engineering (MSE) at City University of Hong Kong (CityU), can rapidly detect contaminants in food within several minutes with concentrations of less than 0.2ppm (parts per million). The new sensor, which can be operated via mobile phone apps, offers rapid and accurate measurements of harmful elements that might be present in some food items such as seafood and meat. With a prototype already in operation, the cost of detecting contaminants is expected to fall.


A sweat sensor to monitor your health

A fully integrated system that simultaneously and selectively measures multiple sweat analytes, and wirelessly transmits the processed data to a smartphone has been developed by the team of researchers at the University of California, Berkeley. Specifically, it is for a flexible sensor system that can measure metabolites and electrolytes in sweat, calibrate the data based upon skin temperature and sync the results in real time to a smartphone. While health monitors have exploded onto the consumer electronics scene over the past decade, this device is the first fully integrated electronic system that can provide continuous, non-invasive monitoring of multiple biochemicals in sweat. This work presents a technology platform for sweat-based health monitors. 


A smart clock that shows you the right information at the right moment

Robotic fish that could enable a closer study of aquatic life

A soft robotic fish, called SoFi, that can independently swim alongside real fish in the ocean has been developed by the engineers at MIT. During test dives in the Rainbow Reef in Fiji, SoFi swam at depths of more than 50 feet for up to 40 minutes at once, nimbly handling currents and taking high-resolution photos and videos using a fisheye lens. Using its undulating tail and a unique ability to control its own buoyancy, SoFi can swim in a straight line, turn, or dive up or down. The team also used a waterproofed Super Nintendo controller and developed a custom acoustic communications system that enabled them to change SoFi’s speed and have it make specific moves and turns.


3D-printed prototype for bionic eye

An array of light receptors on a hemispherical surface has been completely 3D printed by the team of researchers at the University of Minnesota. This discovery marks a significant step toward creating a 'bionic eye' that could someday help blind people see or sighted people see better. Extrusion‐based 3D printing, an emerging technology, has been previously used in the comprehensive fabrication of light‐emitting diodes using various functional inks, without cleanrooms or conventional microfabrication techniques. Here, polymer‐based photodetectors exhibiting high performance are fully 3D printed and thoroughly characterized. The researchers also hold the patent for 3D-printed semiconducting devices.


Robot that carries payloads necessary for search-and-rescue operations

A highly maneuverable search-and-rescue robot that can creep, crawl and climb over rough terrain and through tight spaces has been developed by the team of researchers at Ben-Gurion University (BGUni) of the Negev (BGU). It is called RSTAR. RSTAR stands for Rising Sprawl-Tuned Autonomous Robot. It utilizes adjustable sprawling wheel legs attached to a body that can move independently and reposition itself to run on flat surfaces, climb over large obstacles and up closely-spaced walls, and crawl through a tunnel, pipe or narrow gaps. The innovative new robot was introduced in May at the International Conference on Robotics and Automation (ICRA 2018) in Brisbane, Australia.
