Surface acoustic wave sensors are a class of microelectromechanical systems (MEMS) which rely on the modulation of surface acoustic waves to sense a physical phenomenon. The sensor transduces an input electrical signal into a mechanical wave which, unlike an electrical signal, can be easily influenced by physical phenomena.
AbiliSense (Generic sound recognition technology for a wide variety of use cases, mainly safety and security, and functional in environments such as: home and city). Audio Analytic (AI company whose "Embedded sound recognition AI software gives consumer technology, such as smart speakers, hearables, smart home tech, mobile phones and automotive ...
Machine hearing, also known as machine listening or computer audition is the ability of a computer or machine to take in and process sound data such as speech or music. [8] [9] This area has a wide range of application including music recording and compression, speech synthesis and speech recognition. [10]
Sound Activated Mobile (1968) His first cybernetic work that moved directly and recognisably in response to what was going on around it was the Sound Activated Mobile (SAM). [7] It had four microphones mounted in front of fiberglass parabolic reflectors (reminiscent of a flower) on top of a spine-like column of aluminium castings.
For example, most flying insect preys of bats developed sensitivity to echolocation call frequency. When stimulated by a high-pitched sound, moths engage in dodging flight pathway. Dolphins can also detect killer whales' ultrasonic clicks. In return, killer whales produce more irregular, isolated sonar clicks to make less conspicuous signals. [4]
A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens).
