How has hearing aid sensing changed?
With the U.S. Food and Drug Administration (FDA) rule enabling access to over-the-counter (OTC) hearing aids going into effect on Oct. 17, 2022, many people will want to know the answer to this FAQ [1]. The ruling allows individuals to buy a hearing aid without a medical exam, prescription or professional fitting. Intended to help […]
Bio-inspired MEMS mic targets connected consumer devices
The SKR0400 is the world’s first bio-inspired directional MEMS microphone built for current and future consumer electronics devices. With a powerful combination of performance, audio quality, and a small yet flexible form factor, Soundskrit’s revolutionary new microphone will become the go-to technology for OEMs around the world and reset expectations for consumers for decades to […]
How can you easily evaluate a MEMS microphone ?
Microelectromechanical systems (MEMS) technology is used for many sensing applications including microphones. The MEMS microphone provides a design alternative to Electret Condenser Microphones (ECMs) for many consumer electronic and mobile products. With this goal in mind, Infineon Technologies silicon microphones have been designed to extend the benefits of lowest possible self-noise (high SNR) and lowest […]
What’s the difference between network security and physical security?
Network security involves software and computer-based hardware/firmware to provide access to the authorized and restrict access to the unauthorized. In contrast, physical or brick and mortar security starts with sensors and, if the security system is connected to the internet, it also requires the same network security measures. Protecting a residence, commercial building or an […]
How are ultrasonic MEMS sensors being used for 3D obstacle detection and collision avoidance?
In addition to radar, LiDAR and camera sensing used in 3D obstacle detection and collision avoidance in advanced driver assistance systems (ADAS) in vehicles, ultrasonic sensing has been used as well. Traditionally, the ultrasonic sensors used transducer-based technology to provide a microphone to transmit and receive the ultrasonic signal in passenger vehicle parking applications. Using Infineon’s […]
How can a MEMS microphone be used in harsh environments?
The answer depends on how harsh of an environment and how much protection is required. For a microelectromechanical systems (MEMS) microphone, one of the most-harsh environments is the human body, since sweat and dirt can cause failures in traditional MEMS microphone architectures. Regarding the protection, the International Electrochemical Commission’s (IEC’s) IEC 60529 rating system defines different […]

Can the AgeMeter help you?
Developed by Centers for Age Control, the AgeMeter takes user data and physiological biomarker tests to calculate functional age and provide other age-related feedback to users. Since it tests physiological biomarkers that decline with age, the AgeMeter can validate aging reversal as well as anti-aging therapies for healthcare practices, researchers, fitness programs and consumers. Intended […]
How do microphone sensors fit into a smart home?
A quick search for “sensors in the smart home” can easily identify dozens of sensors – primarily for sensing physical properties. The results could be one of many specific sensing technologies or specific products. For example, one search showed: Fire/CO detection Leak/moisture detection Window & door open and close Video doorbell Smart thermostat Motion sensors […]
