A Microelectromechanical System (MEMS) oscillator is a type of oscillator that integrates mechanical and electrical components at a microscale to generate periodic signals, typically in the form of voltage or current waves. These oscillators leverage the principles of MEMS technology, which combines microfabrication techniques with mechanical design to create tiny devices that can respond to electrical signals with mechanical motion.
A Micromirror Device (often referred to as DMD, or Digital Micromirror Device) is a type of microelectromechanical system (MEMS) technology used to modulate light and create images. It consists of an array of tiny, movable mirrors, each representing a single pixel in an image. These mirrors can tilt to reflect light either toward or away from a projection surface, allowing for rapid and precise control of light intensity and color.
A Microscanner generally refers to a type of compact, handheld device used to scan and analyze small areas or objects, typically at a microscopic level. It combines elements of imaging technology—such as optical systems and sensors—to produce detailed images or data about the sample under investigation. Microscanners can be employed in various fields, including biology, materials science, electronics, and quality assurance, among others.
A nanoelectromechanical relay (NEM relay) is a type of relay that operates at the nanoscale and typically combines mechanical and electronic components to control the flow of electrical signals or power. NEM relays utilize the principles of microelectromechanical systems (MEMS) technology, but on a smaller scale, often harnessing the unique properties and behavior of materials and structures at the nanoscale.
Radio-frequency microelectromechanical systems (RF MEMS) are a type of technology that combines concepts and techniques from microelectromechanical systems (MEMS) and radio-frequency (RF) engineering. RF MEMS devices leverage mechanical structures that can move and respond to electrical signals, enabling the manipulation of microwave and RF signals for various applications.
Smartdust refers to tiny, wireless microelectromechanical systems (MEMS) that can be used to monitor and collect data about their environment. These miniature devices typically include sensors, computational abilities, and communication capabilities, allowing them to interact with each other and share information. The concept encompasses a network of small sensors that can be dispersed over a wide area to collect data on various phenomena, such as temperature, humidity, light, or motion.
A Surface Acoustic Wave (SAW) sensor is a type of sensor that employs surface acoustic waves to detect changes in the environment, such as temperature, pressure, humidity, or the presence of specific chemical substances. SAW sensors leverage the unique propagation characteristics of acoustic waves that travel along the surface of a piezoelectric material, typically a crystal or a thin film.
Surface activated bonding, also known as surface activation bonding or surface activation technology, refers to a method of joining materials that enhances adhesion through the modification of surface properties. This technique is particularly useful in applications where traditional adhesive methods may not provide sufficient bond strength or durability. The process typically involves the following steps: 1. **Surface Preparation**: The surfaces to be bonded are cleaned and prepared to ensure that any contaminants are removed.
Surface micromachining is a technology used to create microstructures and devices on the surface of a substrate, typically silicon, by depositing and etching thin films to form three-dimensional structures.
