Researchers use Graphene for miniature inductors enabling Ultra-Miniaturized Electronics Devices

miniaturizedinductor

The inductors along with capacitors and resistors, inductors are one of the three passive elements that are the foundations of all electronics. An inductor works by inducing a magnetic field as an electric current flows through its coil of wire.…...

Heterogeneous Integration Technology enhance capability of military RADAR, communications, imaging and sensing systems, DARPA’s DAHI, and CHIPS led its development

DARPA CHIPS 1

Modern warfare is increasingly dependent on microelectronics capabilities that sense the environment, convert the signals into data streams, process the information, and generate a response. In this sense, Aerospace and Defense (A-D)  systems are quite similar to commercial systems that…...

New materials bringing Thermoelectric generators or heat-to-power technology close to deployment

IoTsurveiilance

Thermoelectric energy harvesting mainly depends on the operation of the thermoelectric generator (TEG). A thermoelectric (TE) device can directly convert heat emanating from the Sun, radioisotopes, automobiles, industrial sectors, or even the human body to electricity.  A TEG converts heat…...

Superconductors enable new military capabilities from Surveillance, Radars, Communications to electric propulsion

superconductor 9 638

In 1911, a Dutch scientist discovered a class of materials which, at temperatures near absolute zero, could conduct electricity with no resistance and therefore zero loss of power. These materials called Superconductors have unique properties including, Zero resistance to direct…...
