Have you ever wondered what happens in the rainforest when no one is looking?

Magnetic sensor that brooks no interference

A novel magnetic sensor for the first time detects tiny fluctuations in a small magnetic field – even when there is a strong magnet right beside it. The sensor can thus be utilized even in places where power cables generate an interference field – for instance in a car’s side mirror.

New gas sensors for monitoring carbon dioxide sinks

A novel gas sensor system makes it possible to monitor large areas cost-effectively the first time. The patented gas sensor is based on the principle of diffusion, according to which certain gases pass through a membrane faster than others. Using a tube-like sensor it is possible to measure an average gas concentration value over a certain distance without influencing or distorting conditions in the measuring environment.

New cell-based sensors sniff out danger like bloodhounds

A small, unmanned vehicle makes its way down the road ahead of a military convoy. Suddenly it stops and relays a warning to the convoy commander. The presence of a deadly improvised explosive device, or IED, has been detected by sophisticated new sensor technology incorporating living olfactory cells on microchips mounted on the unmanned vehicle. The IED is safely dismantled and lives are saved.

New nanotube sensor can continuously monitor minute amounts of insulin

A new method that uses nanotechnology to rapidly measure minute amounts of insulin is a major step toward developing the ability to assess the health of the body’s insulin-producing cells in real time.

Scientists develop sensors for homemade bombs

harminka — Thu, 20 Mar 2008 03:01:46 -0500

A team of chemists and physicists at the University of California, San Diego has developed a tiny, inexpensive sensor chip capable of detecting trace amounts of hydrogen peroxide, a chemical used in the most common form of homemade explosives.

Epson Toyocom Develops New Pre-Tilted Gyro-Sensor for In-Dash Navigation Systems

harminka — Wed, 07 Nov 2007 04:50:02 -0600

Epson Toyocom Corporation, a leader in the design and manufacture of crystal-based electronic products, today announced that it has developed a new pre-tilted gyro-sensor that can be installed in car navigation systems.

KODAK Announces KAI-01050 Image Sensor for Applied Imaging

harminka — Tue, 06 Nov 2007 10:40:43 -0600

Eastman Kodak Company (NYSE:EK) is enabling a new level of performance for applied imaging markets such as machine vision and scientific imaging with availability of the first in a new family of interline transfer CCD image sensors

Purdue creating wireless sensors to monitor bearings in jet engines

harminka — Wed, 31 Oct 2007 11:34:02 -0500

University, working with the U.S. Air Force, have developed tiny wireless sensors resilient enough to survive the harsh conditions inside jet engines to detect when critical bearings are close to failing and prevent breakdowns.
