Adesto Technologies Corporation and Cadence Design Systems have announced a collaboration to expand the ecosystem around the expanded serial peripheral interface (xSPI) communication protocol to enable higher transfer rates and lower latency for flash memory in IoT devices. The Cadence memory model for xSPI enables use of the octal NOR flash with the host processor in an xSPI system, including ...

Microchip is offering high security IoT authentication to companies with no prior security knowledge, that are producing as few as 10 units. Authentication, in this case, is proving the identity of a device attempting to connect across a network using asymmetric cryptography. Called ‘Trust Platform’, this is a ‘pre-provisioned’ hardware-based secure key storage system, which also offers solutions for mid and ...

Bacteria can grow optically-active tellurium nano-rods, according to the University of Houston. Optoelectronic and photonic devices could benefit. The current discovery grew out of 30 years of basic research, stemming from an initial discovery of selenite-respiring bacteria that form discrete packets of elemental selenium. “From there, it was a step down the periodic table to learn that the same could ...

Researchers at the US National Institute of Standards and Technology (NIST) have used atoms to decode digital signals encoded by phase modulation. The atoms, cesium in this case, are ‘Rydberg atoms’ – atoms that have been wound up into a high energy state that is extremely sensitive to electric and magnetic fields. In this case the atoms were in a vapour cell, pushed ...

Thingy:91 is a cellular and GNSS IoT prototyping platform with world-wide coverage across 700MHz to 2200MHz, created by Nordic Semiconductor and Fractus Antennas. Based on Nordic’s nRF9160 SiP multimode LTE-M/NB-IoT system-in-package with GPS, the battery-powered Thingy:91 comes with a roaming SIM card, 16 sensors and a nRF52840 for short-range wireless communication with Bluetooth 5, Thread, Zigbee and ANT. The SIM is a Nano ...

The Renesas RX65N Cloud Kit is aimed at those prototyping sensor-based IoT end-points with secure links to the cloud

Rockley Electronics is a silicon photonics start-up that recently raised $52m in a funding round, bringing its total to $165m. With all this investor interest, it was time to find out exactly what the company is offering, so Electronics Weekly spoke to its founder and CEO Andrew Rickman – and industry veteran with some history in photonics. In 1988, Rickman founded pioneering ...

UK consultancy 42 Technology has ported a Rust programming language application to a single-chip IoT device, claiming it as a world first. “Rust is a very-high-performance alternative to systems programming languages such C and C++, which avoids the memory safety issues that plague those languages, and without the complexity and overhead of Java,” according to the firm. “It is the ...

Würth is offering a surface-mount single port for 1000Base-T Ethernet industrial LAN connections. Each device contains four sets of inductive components, one for each twisted pair within the Ethernet cable. “WE-LAN AQ transformer convinces in an exemplary fashion in terms of crosstalk, insertion loss, return loss, differential and common-mode rejection,” claimed the firm. This data sheet gives the numbers as: crosstalk ...

Long-term health monitoring of adults, babies and small children without concern for skin injury or allergic reactions is the aim of a project at Georgia Tech, which has produced a stretchy patch that can broadcast electrocardiogram (ECG), heart rate, respiratory rate and motion activity data. Connections are to gold skin-like electrodes through printed conductors that can stretch with the medical ...
