Cell Biology – Biological clocks: Circadian rhythms not dependent on DNA | It has long been assumed that the internal clocks in all living things (loosely called the Circadian rhythm) is associated with DNA. Apparently, they are not. A new study by the universities of Cambridge and Edinburgh (UK) has shown that red blood cells [...]

Measuring heart-rate with microwave sensors

News: Sensor Technology    November 10, 2010
The idea of using microwaves for human body sensors may be just a bit unsettling – think of the microwave oven. However, the device created by Atsushi Mase and Daisuke Nagae of Kyushu University (Japan) uses very low radiation microwaves. It’s a form of RADAR, RF (radio frequency), or Doppler sensor…common enough technology. What’s unusual [...]

SNUPI: Sensory Nodes Utilizing Powerline Infrastructure

News: Sensor Technology    September 20, 2010
SNUPI rhymes with snoopy – you’ll see why in just a moment. Perhaps you’re already familiar with the idea that electrical wiring can be used for a computer network. The technology has never ‘caught on,’ a few people use it though it’s never sold well, however, it works. SNUPI (Sensor Nodes Utilizing Powerline Infrastructure) is [...]

New research: Very touchy sensors

News: Sensor Technology    September 14, 2010
Butterflied sensor……Credit: Linda Cicero, Stanford University News Service Just how hard is it to sense a butterfly alight? On the tip of your finger – no problem. For an electromechanical sensor – impossible, until now. The advance in sensor technology was inspired by an insight: Detection of touch on a membrane (like skin or rubber) [...]

A heart monitor planted in an artery

News: Body Implants    June 2, 2010
The idea of implanting electronics in the human body has its disturbing side, but if anybody had any question what will drive the use of body implants – medical uses – then here’s a confirming story. As reported on ABC World News (May 31, 2010), a device called the EndoSure Wireless AAA Pressure Management System, [...]

Tiny generators for tiny sensors

News: Sensor Technology    April 5, 2010
Nanosensors – sensor devices built at the nanoscale (1/100,000 the width of a human hair) – need energy to run. Nanobatteries are one approach under development. Another technology is nanogenerators, nanoscale devices that create electricity from the mechanical energy provided by the environment such as wave action, wind motion, and body movement. Researchers at the [...]

Sensor technology: Tattletale pills

News: Sensor Technology    March 31, 2010
Tattletale pills, that’s what they call them at the University of Florida (Gainesville, USA) – sensors embedded in pills to indicate whether the pills have been taken or not. The announcement of this new use of technology describes the system as microscale chip and digestible antenna placed in each pill so that ingestion can be [...]

Ultimate sensitivity: Nanosenors

News: Sensor Technology    March 23, 2010
Everything electronic gets smaller, including sensors. Sensors are the devices that gauge your car’s tire pressure. They feel your fingers pinching an iPhone screen. They’re everywhere in modern technology, and soon they will be ultrasensitive and all but invisible – as nanosensors. There are many companies and academic laboratories working on the incorporation of nanotechnology [...]
