Wireless biosensors could relieve health care system burden

A wireless biosensor, developed by a Malmö University researcher, enables a more patient-controlled system whereby infections can be detected much earlier through smart catheters, smart diapers or wound dressings.


Breakthrough in how buildings can promote health and well-being

Having understood the ill-effects if sick building syndrome and the need to better conserve energy by incorporating green features, architects are also utilizing certain elements of an architectural design system shown to ...

Osteoblastic cell stimulation by pulsed electromagnetic fields

Bone fracture healing can be augmented with the application of pulsed electromagnetic fields (PEMFs), but a consensus regarding idealized conditions is lacking. A new study characterizes the in vitro effects of these PEMFs ...

Electromagnetic radiation

Electromagnetic radiation (sometimes abbreviated EMR) is a ubiquitous phenomenon that takes the form of self-propagating waves in a vacuum or in matter. It consists of electric and magnetic field components which oscillate in phase perpendicular to each other and perpendicular to the direction of energy propagation. Electromagnetic radiation is classified into several types according to the frequency of its wave; these types include (in order of increasing frequency and decreasing wavelength): radio waves, microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. A small and somewhat variable window of frequencies is sensed by the eyes of various organisms; this is what we call the visible spectrum, or light.

EM radiation carries energy and momentum that may be imparted to matter with which it interacts.
