The rise of Piezo MEMS: vibrant opportunities and challenges

By Clyde Midelet, PhD Senior Technology & Market Analyst, Sensing ​at Yole Group for LAYERS, powered by EVATEC.

Piezoelectricity is a physical phenomenon that has been utilized for nearly a century. Thin film deposited materials, such as PZT, AlN (with or without Sc doping), KNN, LiNbO₃, and PVDF, are now being widely applied across various industries. Depending on the application, piezoelectric based components can be used for sensing, actuation, or signal transduction (physical to electrical or vice versa). The piezoMEMS device market was valued at $4 billion in 2024 and is projected to grow to $5.7 billion by 2030, at a 6% CAGR24–30.

Today’s snapshot is based on the sensing collection of reports offered by Yole Group. This collection includes the annual report, Status of the MEMS Industry 2025, as well as PiezoMEMS Technologies 2025, Microphones, Microspeakers and Audio Processing 2025, Sensors and Actuators for Wearables 2025, Greater China MEMS Industry 2025, PiezoMEMS Comparison 2025. MEMS devices based on piezoelectric materials are primarily used in applications such as RF filters, inkjet printheads, microphones, voice accelerometers, microspeakers, micromirrors, timing oscillators, ultrasonic fingerprint sensors, and ultrasonic pMUTs (used in imaging, radar, cameras, and Time-of-Flight systems). Among these various devices, significant advancements are expected in MEMS microspeaker technology.

In contrast to the well-established MEMS microphone market, which reached nearly seven billion units in 2024, the MEMS microspeaker market is still in its early stages of adoption, with two million units sold in 2024. MEMS microspeakers compete with well-established legacy technologies such as electrodynamic speakers (ES) and balanced armature (BA) speakers.
