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.

2014
The robust device design of fringing-field electrostatic MEMS actuators results in inherently low squeeze-film damping conditions and long settling times when performing switching operations using conventional step biasing. Real-time switching time improvement with DC-dynamic waveforms reduces the settling time of fringing-field MEMS actuators when transitioning between up-to-down and down-to-up states.

Total Factor Productivity (TFP) measures the efficiency with which inputs are transformed into outputs in production. It is the essence of economic growth, driven by technological advancement. Consider the agricultural sector, where production requires vast amounts of human labor and work animals. Today, modern farm machinery and agriculture technologies have revolutionized how we cultivate crops and produce food much more efficiently. TP = A*f(K, L) TFP is represented as a multiplier 'A' in...
FAQs
In MEMS technology, a sensor detects a physical or chemical change and translates that change into an electrical signal. The signal provides a measurable output from a biological sample or surrounding environment. This conversion principle allows biosensors and other small-scale systems to monitor biological conditions and support rapid analysis.
Lithography defines precise patterns, etching shapes or removes material to form structures and channels, and thin-film deposition adds material in controlled layers. Together, these processes establish the geometry needed for sensors, actuators, microfluidic paths, and other MEMS components. In biological devices, fabrication accuracy influences how samples move and how signals are generated.
The small scale reduces the amount of biological material required for an analysis and can contribute to rapid response. It also makes parallel analysis practical, allowing multiple measurements or conditions to be examined within one device. These features are especially useful when samples are limited or timely results matter.
Microfluidic systems and miniature mechanical structures can support controlled manipulation of cells or biomolecules within a compact platform. This creates a way to study how cellular behavior changes under defined experimental conditions, while integrated sensing can convert relevant physical or chemical changes into electrical readouts. The approach connects manipulation with measurable biological responses.
Fabrication relies on a substrate, often silicon, together with lithography, etching, and thin-film deposition. These processes create precise components and channels that can support sensing, actuation, electronic circuits, and fluid movement. The resulting architecture brings these functions together in a small platform suitable for biological analysis and controlled sample handling.
Applications span diagnostics, drug screening, environmental monitoring, and research on cellular behavior. In diagnostics, these devices can provide compact sensing platforms; in drug screening, their small scale and potential for parallel analysis can support testing across multiple conditions. Environmental monitoring uses the same ability to detect physical or chemical changes electronically.
