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.

Digital Signal Processing for Over-The-Counter Hearing Aids

I wrote a whitepaper looking at the principles of digital signal processing, algorithms,and software that improve hearing for people with hearing loss. This article is intended as an introduction. The complete whitepaper is available for download. The inspiration for this whitepaper comes from the World Health Organization's recent World Report on Hearing (WHO), which shows that 1.5 billion people worldwide have some degree of hearing loss and 430 million people need rehabilitation services. Shockingly, less than 3% (on average worldwide) use hearing aids.
