Meta surfaces can be designed to steer sound or electromagnetic waves in arbitrary directions

PragmatIC, the Cambridge flexible circuit specialist, has announced the first products in its ConnectIC family, the PR1101 and PR1102 flexible integrated circuits (FlexICs), designed for use in closed HF RFID systems. ConnectICs are ultra-thin and flexible and suitable for embedding into a wide range of substrates, including paper and plastic. They have a typical price point of under one cent ...

Rohm has created a reference design for an automotive-grade wireless phone charger with NFC communication, using the Qi standard and supporting EPP (extend power profile) – supplying up to 15W. It combines Rohm’s automotive-grade wireless power transmission control IC (AEC-Q100 qualified BD57121MUF-M) with two STMicroelectronics’ chips, and NFC reader (ST25R3914) and an 8bit microcontroller (STM8A). NFC communication is included for ...

UK-based antenna maker has created an product for wireless lighting that can be used on metal surfaces. Named Magna (part SR4I051) and aimed at industrial IoT and smart buildings, it operates in the ISM 868/915MHz bands. It uses two electrical layers, one isolated from the other, which enables an antenna to radiate on a metal surface or housing  – an ...

To meet demand for Low Power Wide Area (LPWA) IoT connectivity, Gemalto has announced a platform of Cinterion IoT Modules based on the Qualcomm 9205 LTE IoT modem. The modules are designed to support LTE-M and NB-IoT connectivity with optional 2G fallback from a single, ultra-small IoT module. Ready for the latest 3GPP specifications (Rel 14), the platform will be loaded ...

By supporting concurrent communication over BLE and Sub-1GHz wireless, the ST STEVAL-FKI001V1 dual-radio development kit gives the flexibility to envision, build and connect IoT devices like smart sensors, finders and trackers which can be configured, updated, remotely monitored and tracked using various network topologies, protocols and services. Built to unleash creativity for smart-home or smart-building scenarios as well as asset-tracking, energy-management, ...

Radio frequency filters can change which signals they block through a range of frequencies, using an origami-based structure to change their dimensions. Researchers at the Georgia Institute of Technology say that the tunable filters can be used in antenna systems that adapt to ambient conditions in real-time for electromagnetic cloaking systems that could be reconfigured on-the-fly to reflect or absorb different frequencies. Basing the ...

U-blox has announced a multi-band NB-IoT module that supports a preliminary set of 3GPP Release 14 features (LTE Cat NB2). Low power consumption means 10+ years operation on a single primary cell, according to the firm. Called Sara-N3, it is available in two variants: one for China and another that can operate across multiple bands on any NB-IoT network globally. Features ...

At Electronica 2018, we caught up with Samir Hennaoui, of Murata, as part of our promotional coverage for the event.

RF module firm Insight SiP has announced what it believes to be the first fully Bluetooth 5.0 Long Range compliant RF module in a miniature package at Electronica. It measures 8 x 8 x 1mm. Read our full Electronica 2018 coverage » Called ISP1807-LR, it is based on Nordic Semiconductor’s nRF52840 chip and includes a Bluetooth 5 stack with: long range, ...
