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.

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?”
