Low-Cost Method Offers Solution for Small-Volume MEMS Sensor Production

Facebook X LinkedIn Email
Researchers at KTH Royal Institute of Technology have developed a 3D-printing technique for specialized manufacturing of microelectromechanical systems (MEMS). The approach offers a cost-efficient way to manufacture custom-designed MEMS devices, in small volumes, that could be used as sensors in robotics, navigation, and more. Although MEMS technologies can be efficiently produced at high volumes using large-scale semiconductor manufacturing techniques, the manufacture of MEMS components in small and medium-size batches is challenging, due to the high startup cost of manufacturing...Read full article

    3d printing
    3D printing, also known as additive manufacturing (AM), is a manufacturing process that builds three-dimensional objects layer by layer from a digital model. This technology allows the creation of complex and customized structures that would be challenging or impossible with traditional manufacturing methods. The process typically involves the following key steps: Digital design: A three-dimensional digital model of the object is created using computer-aided design (CAD) software. This...
    additive manufacturing
    Additive manufacturing (AM), also known as 3D printing, is a manufacturing process that involves creating three-dimensional objects by adding material layer by layer. This is in contrast to traditional manufacturing methods, which often involve subtracting or forming materials to achieve the desired shape. In additive manufacturing, a digital model of the object is created using computer-aided design (CAD) software, and this digital model is then sliced into thin cross-sectional layers. The...
    two-photon polymerization
    Two-photon polymerization (TPP) is a technique used in additive manufacturing, specifically in the field of 3D printing. It involves using a focused laser to polymerize a photosensitive material in a precise and controlled manner. The process relies on the nonlinear absorption of photons, where two photons are absorbed simultaneously to initiate a chemical reaction that leads to polymerization. Here is a breakdown of the key components and steps involved: Photosensitive material: The...
    polymerization
    Process of synthesizing long molecular chain materials (polymers) by reaction of many small molecules (usually thousands) called monomers.
    accelerometer
    An accelerometer is a sensor or transducer that measures the rate of change of velocity of an object, or in simpler terms, it measures acceleration. Accelerometers are widely used in various electronic devices to detect and measure the acceleration forces acting on the device in different directions. Key features and principles of accelerometers include: Acceleration measurement: The primary function of an accelerometer is to measure acceleration, which is the rate of change of...
    positioning
    Positioning generally refers to the determination or identification of the location or placement of an object, person, or entity in a specific space or relative to a reference point. The term is used in various contexts, and the methods for positioning can vary depending on the application. Key aspects of positioning include: Spatial coordinates: Positioning often involves expressing the location of an object in terms of spatial coordinates. These coordinates may include dimensions such as...
