Small Implanted Device Could Improve Breast Cancer Survival

A small scaffold device is designed to attract breast cancer cells. (University of Michigan College of Engineering) A small device implanted under the skin can improve breast cancer survival by catching cancer cells. The implantable scaffold device is made of FDA-approved material commonly used in sutures and wound dressings. It’s biodegradable and can last up to two years within a patient.

Flexible Electronic Skin Patch Monitors Alcohol Levels

The alcohol sensor consists of a temporary tattoo (left) and a flexible printed electronic circuit board. Engineers at the University of California San Diego have developed a flexible wearable sensor that can accurately measure a person’s blood alcohol level from sweat and transmit the data wirelessly to a laptop, smartphone or other mobile device. The device can be worn on the skin and could be used by doctors and police officers for continuous, non-invasive and real-time monitoring of blood alcohol content.

New NASA Instrument Measures Greenhouse Gases

Mark Stephen (left) and Tony Yu are part of the team that developed the advanced laser system used on the CO2 Sounder Lidar. (NASA's Goddard Space Flight Center/Bill Hrybyk) NASA scientists and engineers have built an instrument powerful and accurate enough to gather around-the-clock global atmospheric carbon-dioxide (CO2) measurements from space. The CO2 Sounder Lidar operates by bouncing an infrared laser light off the Earth’s surface. Like all atmospheric gases, carbon dioxide absorbs light in narrow wavelength bands — in this case, the infrared. By tuning the laser to the infrared, scientists can detect and then analyze the level of carbon dioxide in that vertical path.

Sensors Measure Power Use by Each Device in a Household

Researchers at MIT have developed a device and software that could figure out exactly how much power is being used by every appliance, lighting fixture, and device in a home. (Bryce Vickmark) New postage-stamp-sized sensors developed at MIT measure exactly how much power is being used by every device in a household. No wires need to be disconnected, and the placement of the sensors over the incoming power line does not require any particular precision. The sensors pick up so much information about spikes and patterns in the voltage and current, that the system can tell the difference between every different kind of light, motor, and other device, and show exactly which ones go on and off at what times.

New at IMTS

Optomec (Albuquerque, NM) unveiled its LENS machine tool machines that integrate the company's metal 3D printing technology into standard CNC machine tool platforms. Three standard system configurations are offered, making hybrid and traditional metal additive manufacturing more affordable and accessible. The three systems are open-atmosphere, hybrid additive and subtractive, and an inert system with a hermetically sealed chamber.
