Acoustic Metamaterials breakthroughs enable acoustic clocking, super-lensing , sound focusing and confinements

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. They are predicted to be able to protect the building from earthquakes by bending …

Nanolasers emerging technology for  optical interconnects, near-field spectroscopy and sensing, optical probing for biological systems, microprocessors and quantum circuits

Lasers are widely used in household appliances, medicine, industry, telecommunications and more.  A nanolaser is a laser that has nanoscale dimensions. These tiny lasers can be modulated quickly and, combined with their small footprint, this makes them ideal candidates for on-chip optical computing.   Several years ago, scientists introduced nanolasers …

Graphene enables room temperature single photon emitter and detector for unhackable Quantum Key Cryptography (QKD)

Quantum Key Distribution, or QKD, enables two remote parties, “Alice” and “Bob”, who are connected by a passive optical link to securely generate secret key material. Single-photon sources (SPSs) and single-photon detectors (SPDs) are key devices for enabling practical quantum key distributions (QKDs).  Single photon generation is necessary for secure quantum transmission; …

DARPA DeMi developing technologies for space based telescope on it’s military CubeSat satellite for Space Surveillance Awareness

The volume of space between the Earth’s surface out to geosynchronous orbit is enormous—equivalent to 240,000 times all the Earth’s oceans. Yet the number of objects calling that volume home is growing all the time—not just with satellites but with debris of all kinds, natural and manmade. And keeping track …

Printed electronics breakthroughs leading to Printed and flexible electronics (PFE) revolution

While the conventional electronics like computers and smartphones is built around silicon integrating billions of transistors and is manufactured using complex, costly and wasteful processes in multi-billion dollar foundries , The printed and flexible electronics aim to replace this by “organic” semiconductors which are long chains of thousands of repeating …

Nanotechnology for Bulletproof and Armor Materials

In order to defeat a threat, armor systems are designed to: deform/deflect the threat; dissipate energy; and prevent residual debris penetration. Most anti-ballistic materials used in bullet-proof jackets or explosion-proof blankets are made of Kevlar, Twaron or Dyneema fibers, which stop bullets from penetrating the surface by spreading and absorbing …

Reconfigurable or Adaptable Electronics technologies based on Nanotechnology enable resilient systems for Extreme Environments and multi-function adaptive military systems

Traditionally, electronics have been designed with static form factors to serve designated purposes. This approach has been an optimal direction for maintaining the overall device performance and reliability for targeted applications. As the world enters the age of ubiquitous computing, the need for reconfigurable hardware operating close to the fundamental …
