Source: Shreyas Narsipur, Mechanical and Aerospace Engineering, North Carolina State University, Raleigh, NC Fluid pressure is an important flow characteristic that is required to determine the aerodynamics of a system. One of the oldest and still existing pressure measurement systems is the manometer due to its accuracy and simplicity of operation. The manometer is generally a U-shaped glass tube that is partially filled with liquid, as shown in Figure 1. The U-tube manometer requires no...

A novel technique to record the pressures within the skull is described. The minimally invasive method uses a fibre-optic pressure sensing system to accurately measure intracranial pressure (ICP) in anaesthetized rats without causing significant brain trauma. The technique may be used in a wide range of experimental models.

In this protocol we describe production, purification and titration of lentiviral vectors. We provide an example of lentiviral vector-mediated gene delivery in primary cultured neurons and astrocytes. Our methods may also apply to other cell types in vitro and in vivo.
FAQs
The applied pressure deforms the sensing element, and that deformation changes an electrical property such as resistance, capacitance, or piezoelectric charge. A conversion stage then expresses the change as a calibrated electrical output. This chain links mechanical loading to quantitative monitoring in physiological systems and engineered equipment.
These responses are alternative electrical signatures of sensing-element deformation. A resistance change, capacitance change, or piezoelectric charge can serve as the measurable intermediate between applied pressure and the final signal. The choice identifies how the transducer represents pressure electrically, while calibration makes that representation quantitatively useful for monitoring biomedical pressures and forces.
High sensitivity allows the device to detect pressure-related changes with useful resolution, while a small form factor supports integration into medical devices and laboratory models. Continuous measurement supplies an ongoing record rather than a single reading, which is valuable for physiological monitoring and system control. Together, these attributes connect measured pressure to device performance.
A basic workflow begins by applying or exposing its sensing element to the pressure of interest. The resulting electrical change is captured, converted into a calibrated output, and interpreted as a quantitative pressure measurement. In bioengineering, this sequence can be used to monitor physiological pressures or evaluate pressure-related behavior in devices and models.
Applications include blood pressure, respiratory pressure, fluid flow, and forces within medical devices or laboratory models. The same measurement principle therefore supports both physiological monitoring and engineering assessment. Its output can provide quantitative information for examining pressure or force behavior where continuous measurement is useful.
In these systems, the transducer supplies pressure information that can be monitored during operation. Ventilators and infusion pumps are examples of systems whose performance can be supported or controlled with such measurements, while bioreactors provide a laboratory context for pressure monitoring. The resulting data help connect system behavior with measured mechanical conditions.
A calibrated output converts the sensing response into a quantitative value that can be compared across physiological monitoring, device operation, or laboratory-model experiments. During validation, this makes pressure or force behavior observable rather than purely qualitative. Researchers can use the measurements to assess medical devices and engineered systems while maintaining a direct link to the underlying mechanical load.
