Salt grain size cameras have great potential to spot problems in the human body and enable sensing for super-small robots. Enabled by a joint design of the camera’s hardware and computational processing.

While a traditional camera uses a series of curved glass or plastic lenses to bend light rays into focus, the new optical system relies on a technology called a metasurface, which can be produced much like a computer chip.

The work was supported in part by the National Science Foundation, the U.S. Department of Defense, the UW Reality Lab, Facebook, Google, Futurewei Technologies, and Amazon.

The Australian LAVO developed the first world home hydrogen system. It fills small tanks with hydrogen using water and solar energy.

LAVO asked Studio MOM, in the Netherlands, to design a super-lightweight e-bike with this system.

• All technical elements can be assembled like Lego blocks.
• The concept is easily adaptable: from city bike to transport bike for small business use.
• The technology has been cleverly incorporated into the frame. Just look at the lighting units.

Certification strategies are gaining widespread customer support and constitute
an important vector in changing how food will be obtained and distributed in the future.

Third-party certification (TPC) differs from first and second party certification mainly
because the third-party authority that issues the certificate has no interest in the transaction.

Third-Party Certification of Agri-Food Supply Chain Using Smart Contracts and Blockchain Tokens is a paper that answers this research questions:
RQ1: “Is it possible to establish a harvest TPC mechanism with tamper-resistant certificates
easily available to anyone, even previously unknown food supply chain stakeholder via
mobile devices?”
RQ2: “If one such mechanism is possible, who will carry the data input and maintenance
costs? In other words, how will each stakeholder be incentivized to use this mechanism?”
RQ3: “If one such mechanism is possible, what would be the typical time for the response
to a certification query, in other words what quality of service can be expected by the
end consumer?”
