    What are MEMS, and how do they work?

    MEMS stands for microelectromechanical systems. This refers to miniaturized systems that combine electrical and mechanical functions in a very small space.

    Many people use MEMS every day without even realizing it: For example, when a smartphone screen rotates automatically, it’s MEMS sensors that detect the device’s movement and acceleration and adjust the screen orientation accordingly. Similar micromechanical sensors and actuators are used in many other applications, ranging from hearing aids and medical sensors to print heads in inkjet printers.

    Design and operating principle

    A MEMS component typically consists of three functional areas: a micromechanical structure, a sensor or actuator element, and an electronic evaluation unit. Mechanical quantities such as acceleration, pressure, or sound cause a structure to change on the micrometer scale—this change is detected electrically and then processed by integrated circuits.

    As such, MEMS combine the mechanical response of a microcomponent with the signal processing capabilities of semiconductor technology. The Fraunhofer IMS describes MEMS as innovative microelectronic and micromechanical systems.

    Advantages and limitations

    MEMS enable compact designs, low power consumption, and high-volume production, and make it possible to integrate sensors directly into electronic systems. Limitations arise from factors such as temperature, vibration, humidity, contact with media, long-term drift, aging, and packaging, among others. For this reason, developers should always evaluate MEMS sensors within the target system, rather than in isolation at the component level.

    How are MEMS manufactured?

    MEMS are manufactured on silicon wafers, similar to semiconductor chips. Because their structures are only a few micrometers in size, the process utilizes techniques from microtechnology and semiconductor technology. This allows many identical MEMS components to be produced in parallel on a single wafer – with precision, reproducibility, and in large quantities.

    Wafer-based manufacturing

    Many MEMS are based on a silicon wafer, upon which the sensor or actuator structures are built up layer by layer. Depending on their function, these result in moving masses, membranes, channels, electrodes, or cavities. Silicon is particularly well-suited for this purpose because it is mechanically stable, able to be electrically integrated, and easy to process industrially.

    Microstructuring via photolithography

    A key step in MEMS production is photolithography. In this process, a machine applies a light-sensitive layer—known as photoresist—to the wafer. The paint is then exposed to light through a mask. The mask determines which areas will be retained and which will be removed.

    Etching processes for fine structures

    After photolithography, a machine etches the exposed areas. In this process, material is selectively removed to create micromechanical structures through wet-chemical or dry-chemical processes. Depending on the processing, the resulting structures may be more directional and vertical, or they may be more deeply etched.

    Deposition of functional layers

    In addition to removing material, new layers are also deposited during MEMS production. These are able to perform electrical, thermal, piezoelectric, magnetic, or mechanical functions.

    Bonding and cleanroom manufacturing

    Many MEMS consist of several layers or wafers that are bonded together. All production steps take place in a cleanroom, since even the smallest particles can impair the functionality of the microstructures.

    In which sectors are MEMS used?

    Automotive

    In vehicles, MEMS measure, among other things, acceleration, rotational rate, and pressure, as well as environmental parameters such as humidity, temperature, and gas concentration. MEMS help to deploy airbags, regulate the Electronic Stability Program (ESP) and engine management, and control driver assistance systems.

    Consumer electronics

    Devices such as smartphones, smartwatches, headphones, cameras, and augmented/virtual reality (AR/VR) systems use MEMS for motion detection, audio recording, image stabilization, altitude measurement, and control functions. Bosch points out that MEMS sensors are found in about half of all new smartphones, for example.

    Industry & IoT

    In industry, MEMS enable compact sensor nodes for applications such as condition monitoring, process monitoring, robotics, and predictive maintenance. For IoT applications, factors such as energy efficiency, the degree of integration, and cost per measurement point are particularly crucial.

    Medicine & microfluidics

    In medical technology, MEMS are used in applications such as pressure sensors, dosing systems, implants, “lab-on-a-chip” systems, and microfluidic analysis platforms. In addition to a very high degree of precision, key requirements here also include high biocompatibility, efficient validation, and high resistance to media.

    Which MEMS technology is right for my application?

    Choosing the right technology for a given application depends primarily on what physical quantity is being measured and where it will be used. For example, an acceleration sensor measures linear acceleration, a gyroscope measures angular velocity, a pressure sensor measures pressure differences or absolute pressure, and a MEMS microphone measures sound pressure. Complex systems, such as in inertial measurement units, often combine multiple types of sensors.

    Key criteria for making a decision are:

    • Measurement range
    • Resolution
    • Precision
    • Temperature behavior
    • Long-term stability
    • Noise
    • Energy demand
    • Interfaces
    • Design
    • Costs
    • Availability
    • Certifications

    Some common mistakes made during the selection process include focusing too narrowly on datasheet values, failing to adequately evaluate the packaging, lacking a calibration strategy, and placing the component in an unfavorable location on the circuit board. Developers should therefore always test MEMS within the overall system.

    Trends and innovations in MEMS technology

    MEMS are increasingly evolving from individual sensor components into highly integrated system components. Future development will focus on smaller designs, lower power consumption, higher measurement accuracy, more robust packaging, and closer integration of sensor technology, electronics, and data processing.

    Miniaturization and integration

    The increasing level of miniaturization is still a key trend. MEMS are no longer being viewed merely as individual sensors, but as part of an overall system consisting of a chip, a housing, electronics, and software. Processes such as wafer-level and post-CMOS processes, as well as 3D integration, support this development because they combine MEMS structures directly with electronic circuits.

    Smart sensors and sensor fusion

    Another trend is moving intelligence closer to the sensor, which is usually referred to as “smart sensors” or “sensor fusion.” Modern MEMS don’t just provide raw data; they can also preprocess measurement values, reduce noise, or combine data from multiple sensors. This reduces the volume of data, energy consumption, and system complexity, especially in wearables, IoT sensor nodes, and mobile devices.

    New materials.

    In addition to silicon, new materials and combinations of materials are becoming increasingly important. These include piezoelectric, biocompatible, flexible, and particularly durable materials, which enable MEMS with new properties, such as those for medical applications, flexible sensors, high-temperature environments, or chemical measurement tasks.

    Microfluidics and bio-MEMS

    Bio-MEMS and microfluidic systems are a dynamic field of innovation. They make it possible to precisely control minute volumes of liquid and are used in applications such as diagnostics, “lab-on-a-chip” systems, drug dosing, cell analysis, and point-of-care applications.
