Long and hollow glassy carbon microfibers were fabricated based on the pyrolysis of a natural product, human hair. The two fabrication steps of carbon microelectromechanical and carbon nanoelectromechanical systems, or C-MEMS and C-NEMS, are: (i) photolithography of a carbon-rich polymer precursor and (ii) pyrolysis of the patterned polymer precursor.

2025
This video demonstrates chip-based digital PCR — a variation of the digital PCR technique that is useful in detecting rare transcript variants. The PCR reaction is partitioned into the chambers of a nanofluidic chip, each of which acts as an independent reaction. The detection of fluorescence signals from the chambers with amplified targets confirms the presence of rare transcript variants in the sample.

Introduction to Organ-on-Chip Models Organ-on-chip models are advanced microphysiological systems that recreate key structural and functional features of human organs in a controlled laboratory setting. These devices integrate living human cells within microfluidic channels, allowing researchers to simulate tissue–tissue interfaces, fluid flow, and mechanical forces that are essential for normal organ function. Unlike traditional cell cultures, which often lack these dynamic physiological cues,...
FAQs
The sensing chain begins when a microscopic mechanical element experiences acceleration, pressure, vibration, or sound. That physical response is converted into an electrical signal by the integrated device, allowing downstream electronics to represent the measured condition. This transduction links a physical input to usable engineering data for monitoring, control, or analysis.
Sensing uses a physical input to produce an electrical output, whereas actuation uses an electrical signal to produce mechanical motion. This bidirectional relationship allows one device architecture to detect conditions or create movement, depending on how its mechanical structures and electronic circuits are configured. The distinction supports functions such as optical switching and controlled mechanical response.
Integration places physical structures, sensing or actuating elements, and electronic circuits on a semiconductor substrate within one miniature device. This arrangement supports compact designs, low power requirements, and fast response while remaining suitable for mass production. For engineering systems, those characteristics help incorporate physical measurement or motion functions into space-constrained equipment.
Microfabrication provides the manufacturing basis for forming the microscopic mechanical components and their associated electronic circuitry on a semiconductor substrate. Because the device depends on structures at very small scales, this fabrication approach enables functions that would be difficult to achieve with larger components. It also supports the repeatable production of miniature devices for engineering systems.
The required physical measurement or motion determines the appropriate MEMS function. Accelerometers and gyroscopes support motion-related applications, while microphones respond to sound and pressure sensors measure pressure conditions. Optical switches provide controlled optical movement, and microfluidic systems support fluid-handling functions. These examples show how one technology family serves distinct engineering requirements.
Their small size, low power requirements, fast response, and mass-production suitability make MEMS chips practical across many system types. Mobile devices and vehicles can incorporate motion-sensing functions, while medical instruments and industrial monitoring equipment can use physical measurements such as pressure or vibration. The same engineering advantages also support emerging autonomous technologies.
