MEMS Sensors Steadily Displace Legacy Electret Capsules
Device manufacturers across major consumer electronics markets are increasingly specifying MEMS acoustic sensors positioned against legacy electret capsule designs, responding to demand for smaller physical footprints that fit within increasingly compact smartphone, hearable, and wearable device housings. This shift has required suppliers to invest in silicon foundry engineering and acoustic performance validation capability, a process that can take twelve to eighteen months per sensor generation given required reliability certification. Device manufacturers are increasingly treating MEMS specification as a competitive prerequisite for new product design, accelerating the transition well beyond electret retention.
