energyGraphene foam for wearables and with scalable 3D production

A Glasgow University team has developed medical sensors powered by a porous foam of graphene and silver, an advance with potential applications in the wearable device market. They used a commercially available graphene foam to make a layered structure with …

darpaDARPA challenges : describe limits of quantum computing and apply QC to improve machine learning

DARPA Defense Sciences Office (DSO) is seeking information on new capabilities that could be enabled by current and next-generation quantum computers for understanding complex physical systems, improving artificial intelligence (AI) and machine learning (ML), and enhancing distributed sensing. The field …

3d printingOrganic ionic ink can make 3D printed sensors for soft robots

Integrating sensors within soft robots has been difficult in part because most sensors, such as those used in traditional electronics, are rigid. Harvard researchers developed an organic ionic liquid-based conductive ink that can be 3D printed within the soft elastomer …

lasersPhotonic precision measurement chip shows mass production of quantum sensors is possible

Researchers at the National Institute of Standards and Technology (NIST) have created a chip on which laser light interacts with a tiny cloud of atoms to serve as a miniature toolkit for measuring important quantities such as length with quantum …

cameraWorldview Stratollites are commercial high altitude balloons like Google Loon – Worldview had an explosion December 2017

World View Stratollites offer all the advantages of high-altitude balloons – low-cost, rapid deployability, and low-impact flight – with an innovative new development: the ability to fly a variety of trajectories – from circumnavigating the Earth to persistence over a …

businessPregnant Women can pee on an Ikea ad for half price on cribs

The magazine Ikea ad, running in Sweden, encourages the reader to pee on it. If she does so, and is pregnant, the ad reveals previously invisible text offering a discounted price on a crib—using similar technology that pregnancy tests use …

carsResolution of self driving car sensors improved 1,000-fold to detect objects through fog

The MIT Camera Culture group present a new approach to time-of-flight imaging that increases its depth resolution 1,000-fold. That’s the type of resolution that could make self-driving cars practical. The new approach could also enable accurate distance measurements through fog, …

futureRoadmap for Future Ocean Floor Mapping

About 71% of the Earth is covered by the World Ocean for which the bottom topography (bathymetry) is far less known than the surfaces of Mercury, Venus, Mars, and several planets’ moons, including our own. Mapping through ocean water deeper …

appUltrasound on a chip using an array of sensors will make ultrasound 50 times lower cost in 2018

A regular ultrasound machine costs over $100,000 but a new ultrasound on a chip device attached to smartphone will be $2000 in 2018. It will be portable and will eventually make ultrasound as common as blood pressure cuffs in hospitals, …

lasersPlasmons in an Open Box Create Miniature Laser for fantastic sensors

Scientists at the National Institute of Standards and Technology (NIST) have developed the first miniature laser in which the light is guided along the floor of an open metallic trench. The laser could act as a nanoscale device to sense …
