This is a nice one - the "Enviro + Air Quality" which works with your Raspberry Pi. It gives you information about your local indoor environment, including air quality measurements.

Nanusens has demonstrated a mems digitally-tuneable capacitor for 5G and 6G RF front-ends, that is compatible with CMOS IC processing and can be integrated with circuitry. The Q-factor is above 100 at 1GHz, and the four-bit capacitor has a minimum capacitance of 450fF (30fF/capacitor) with them all off and tunes up to ~1pF – a capacitance ratio of 2.2 which ...

Rogue Valley Microdevices, the Oregon pure-play MEMS foundry, has announced that its second 50,000-square-foot fab, currently under construction on the “Space Coast” of Florida will be 300mm capable and running wafers in 2025. The company claims it will be the first pure-play foundry with 300mm capability. “With Rogue Valley Microdevices’ investment in 300mm MEMS capability at our new Palm Bay, ...

Bosch Sensortec says it has launched the world’s smallest MEMS accelerometers – the BMA530 and BMA580. BMA530 tracks activities with its step counter and is  suitable for wearables, and BMA580 targets hearables with voice activity detection. Compared to Bosch’s current generation accelerometer (BMA253), the BMA530 and BMA580 have a 76 percent smaller footprint and have been reduced in height from 0.95 mm ...

XMems Labs has revealed a mems-based loudspeaker that uses ultrasonics to reproduce bass notes. Branded ‘Cypress’, the company describes it as “full-range” and said that it “achieves >140dB low frequency SPL [sound pressure level] enabling a no-compromise replacement for coil speakers in noise-cancelling earbuds”. In an earbud, there would be three parts: a conventional wireless earbud receiver IC, a custom ...

Akoustis Technologies, a maker of RF bulk acoustic wave (BAW) filters, has launched foundry service making filters for wireless markets including phones, Wi-Fi, military, 5G infrastructure and automotive. Using 150mm silicon substrates, its process, XB1, covers 1.6 to 7GHz and can handle up to 4W CW (continuously) – plus it has XP3F in the pipleline aimed at 7 to 20GHz ...

Pickering Interfaces has teamed up with Menlo Microsystems to introduce MEMS switching to a range of PXI and PXIe RF multiplexer modules. “MEMS-based RF multiplexers deliver increased operational life – up to 300x, faster operating speed – up to 60x, higher bandwidth and increased RF power handling versus traditional electromechanical relay alternatives,” according to Pickering. “Insertion loss remains comparable with ...

CUI has three new micromachined omnidirectional microphones for portable devices and wearables, that can work across 20 to 20,000 Hz. CMM-2718AB-38162W-TR, CMM-2718AB-38164W-TR and CMM-2718AT-38164W-TR are analogue mems microphones with accurate -38dB ±1dB sensitivity ratings. There are top or bottom port versions, in packages down to 2.75 x 1.85 x 0.9mm, that can be reflow soldered. Acoustic overload point (AOP) is ...

Nanusens has designed an all-digital capacitance measurement circuit to integrate alongside its MEMS sensors. “This means that both the sensor structure and its detection circuitry can be made at the same time within a chip using standard CMOS processes on whatever process node is required,” said the Devon, UK company. “As a result, ASICs can now be made with several ...

Timing devices provide a mission-critical function in automotive systems. Even if a component or system goes awry, EMS clocking signals must continue operating without fail, says Etienne Winkelmuller, of SiTime. Vehicles are designed to work reliably for many years while operating in harsh conditions. If a component or system malfunctions, the vehicle is still expected to operate safely and reliably ...
