OmniBuds Hearables Project by Nokia Bell Labs Backed by Cambridge Future Tech

OmniBuds are the world's first hearables designed to continuously monitor all 5 vital signs, complemented by state-of-the-art augmented hearing capabilities. Conceived by Nokia Bell Labs in Cambridge, UK, the OmniBuds project is now receiving further support from venture builder Cambridge Future Tech. The company entered into a relationship with Nokia Bell Labs and Nokia Ventures & Partnerships to establish OmniBuds Ltd for the commercialization of the OmniBuds platform, as a fully featured ear-worn AI/ML computing platform.

It was a big product announcement from Analog Devices at Sensors Converge 2024, but aside for what was revealed to those attending the event, there has yet to be a formal announcement. The ADXL380 and ADXL382 are low noise, low power, wide bandwidth, 16-bit sensors that cover a dynamic range of 85dB, making them good options for precision applications with minimal calibration, with the ADXL380 being ideal for new true wireless ANC earbuds. audioXpress explores here all the important details about these two new 3-axis MEMS accelerometers.

Available now, the all-new Sennheiser MOMENTUM Sport earbuds were developed for athletes and sports enthusiasts, and combine state-of-the-art integrated biometric sensors with superior sound quality.​ Unlike many other fitness-oriented products that basically focus on ingress protection and staying in place, the new Sennheiser MOMENTUM Sport earbuds are a premium ANC design that is intended to be both motivational and useful when combined with the leading tracking and training platforms.

Azoteq recently expanded its offering to the TWS market with the release of the IQS323. The IQS323 offers capacitive and inductive sensing as user interface and in-ear-detection, whilst the IQS7222A IC is a multifunctional capacitive, inductive, and Hall-effect sensor with additional temperature sensing for reference tracking. The IQS7222A is offered in a 1.62 x 1.62mm WLCSP and allows you to add a touch-and-swipe interface, wear detection, docking detection and your choice of an inductive waterproof button or the inductive force-sensing features.

Danish measurement microphone specialists GRAS Sound & Vibration, now a part of Axiometrix Solutions, announced two new microphones with SysCheck2 functionality allowing for remote-controlled health check of an entire measurement chain. The new microphones are the GRAS 246AE 1/2" CCP Free-field Standard SysCheck2 Microphone Set, and the GRAS 246AO 1/2" CCP Pressure Standard SysCheck2 Microphone Set, both featuring self-verification.

Azoteq recently released its second-generation four-in-one chip for earbuds. The IQS7222A IC is a multifunctional capacitive, inductive, and Hall-effect sensor with additional temperature sensing for reference tracking. The 1.62 x 1.62 mm chip allows you to add a touch-and-swipe interface, wear detection, docking detection and your choice of an inductive waterproof button or the inductive force-sensing features.

In the February 2015 issue of audioXpress, Mark Driedger discussed a tube power amplifier controller based on the Arduino open-source microcontroller. In this follow-up article, Mark Driedger explains how to use some of the Arduino’s untapped capabilities to incorporate the bias meter into the amplifier controller with virtually no additional hardware. A temperature sensor and over-temperature shut-down capability are also included. This article was originally published in audioXpress, May 2015.
