STMicroelectronics Announces All-in-One Motion and Bone-Conduction Sensor for Hearables

STMicroelectronics has announced the LSM6DSV16BX, a unique highly integrated sensor that delivers important space savings inside hearable devices or general-purpose TWS earbuds, including for sports. The new device delivers longer listening experiences and superior hearing by combining a 6-axis inertial measurement unit (IMU) for head tracking and activity detection with an audio accelerometer for detecting voice through bone conduction in a frequency range that exceeds 1KHz.

Nanusens has had its first patent granted in the US, with filings in other countries underway, and has more patents in the process of being applied for. These all protect the company's innovative technology of building nanoscale structures within a standard CMOS metal layers to create novel NEMS (Nano Electro Mechanical Systems) sensors. Nanusens recently appointed Dr Graham Hine as Chairman with the goal of driving growth and fund raising for the nanosensors company.

Demand for True Wireless Stereo (TWS) products reflect the growing demand for multi-function, health care, and connected wearable solutions, all requiring smaller and longer battery life devices. Asahi Kasei Microdevices (AKM) has recently introduced the AKM AK4336ECB ultra low power audio codec, a 4-channel ADC and one channel DAC that supports active noise cancelling designs, complementing its complete portfolio of audio systems and sensors for TWS development.

Sony Electronics announced the WF-SP800N sport headphones, its newest truly wireless noise canceling model. Designed for an active lifestyle, the WF-SP800N allows users to run, workout at the gym, and enjoy improved music experiences with a secure fit, IP55 rating for water and dust resistance, and long battery life. Based on the same Bluetooth chip from the successful WF-1000XM3, the new WF-SP800N model adds interesting audio processing and personalization feature, with support for 360 Reality Audio.

The hearables market is exploding, growing at a CAGR of 37.6%. And, like nearly all wireless devices, hearables need low-latency motion sensors in order to not only perform their critical functions but also enable a variety of enhanced features that improve the user experience. This article takes a look at five key features that a sensor must have in order to deliver enhanced functionality such as activity tracking.
