xMEMS Achieves Extended Bass Response, Making ANC Applications Possible From a Single MEMS Driver

The new Cypress MEMS speaker from xMEMS Labs achieves 40X louder bass response on a single monolithic, miniaturized device, achieving well above the 130dB SPL at low frequencies, required for ANC implementations on TWS earbuds. The new xMEMS Cypress achieves this groundbreaking performance by using ultrasound technology. The new development will be demonstrated at CES 2024 by appointment only, with mass production scheduled for late-2024.

Nanusens Announces That It Can Now Create ASICs With Embedded Sensors

Nanusens has announced that it has successfully created a fully digital circuit design to measure the capacitance of its nanosensors. 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. As a result, ASICs can now be made with several different sensors embedded within them, helping to expand MEMS applications in hearables.
