The dawn of the first-generation iPhone marked a pivotal moment in technology – it showcased the remarkable power of accelerometers. These sensors, abbreviated as MEMS (Micro Electronic Mechanical Systems) accelerometers, have since infiltrated diverse electronic design realms. This article delves into the world of MEMS accelerometers, unveiling their wide-ranging applications and highlighting their significance in modern electronics.


The Motivation Behind MEMS Development

To understand the essence of MEMS development, one can turn to Kovacs's seminal work, "Micromachined Transducers Sourcebook". While primarily focused on manufacturing processes, the book encapsulates the core motivation behind MEMS advancement: "… micromachined transducers are generally those that are fabricated using tools and techniques intended for the integrated circuit industry..."


Excursus: MEMS technology is more

Though this article predominantly explores accelerometers, the domain of MEMS technology is expansive, encompassing microphones, barometers, optical switches, mirror-based displays, and even more innovative applications. MEMS microphones, for instance, have undergone revolutionary construction, resulting in size reduction and enhanced Signal-to-Noise Ratio (SnR). This trend mirrors the progress in MEMS accelerometers, with the only drawback being the need for higher sensitivity amplifiers due to the comparatively lower signal voltage.
