Developing Sensors to Assess Blast Effects on Soldiers
Posted in Sensors, Detectors, Medical, News, MDB on Thursday, May 09 2013
There are two parts to a blast created by an improvised explosive device: a shock wave traveling at supersonic speed, and compressed air, which travels in front of the shock wave. Both can cause considerable damage to the human body, but the exact effects are unclear. To prevent injuries to soldiers and provide better care to those who are injured, the U.S. military wants to understand how blasts impact the human body. So it is working with the Georgia Tech Research Institute to develop a system that measures the physical environment of an explosion and collects data that can be used to correlate what the soldier experienced with long-term medical outcomes, especially traumatic brain injury.

NASA Technology

You wouldn’t find a big bowl of spaghetti served on the International Space Station (ISS). In microgravity, it would be a complete mess. There is, however, something like spaghetti on the ISS: the wires that connect electrodes for an electrocardiogram (EKG). They can be just as much of a nuisance for the crew members.

Sensordrone Tricorder Platform for Consumers and Mobile Device Developers
Mark Wagner
Sensorcon, Inc., Buffalo, NY

The Sensordrone, an invention that dramatically extends the sensing capabilities of smartphones and tablets, came out of the Consumer Products category, but could well have been entered in almost all of the categories because of its versatility. The keyfob- sized device includes sensors that enable consumers to run a variety of medical applications — from blood pressure monitoring to temperature sensing to breath alcohol testing. But, in addition to medical uses, the device is open to a wide range of applications, depending on whether it’s for home safety use, medical use, industrial, or construction use. It could be used to monitor carbon monoxide, humidity, light, and weather, or as an altimeter, barometer, stud-finder, data-logger, and more.

Bioactive Coating Camouflages Implants for Deep Brain Stimulation
Posted in Imaging & Diagnostics, Implants & Prosthetics, Materials / Adhesives / Coatings, Biosensors, Treatment Devices, Sensors, Medical, Features, MDB on Monday, October 01 2012
Brain-computer interfaces are at the forefront of treating neurological and psychological disorders, in cluding Parkinson’s, epilepsy, and depression. Among the most promising technologies is deep brain stimulation (DBS) — a method in which an implanted silicon chip ejects high frequency currents under the skin that are transferred to the brain through implanted electrodes that send and receive signals. Approximately 30,000 people worldwide are currently using DBS. But to ensure that the signals are properly sent and received requires a smooth interaction between the brain and the hardware.
