Analysis of the contractile properties of chemically skinned, or permeabilized, skeletal muscle fibers offers a powerful means by which to assess muscle function at the level of the single muscle cell. In this article we outline a valid and reliable technique to prepare and test permeabilized skeletal muscle fibers in vitro.

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.

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...

The non-nutritive suck (NNS) device can easily collect and quantify NNS features using a pacifier connected to a pressure transducer and recorded through a data acquisition system and laptop. Quantification of NNS parameters can provide valuable insight into a child's current and future neurodevelopment.
FAQs
The elastic element serves as the mechanical link between an applied load and the recorded signal. When the load causes slight deformation, a strain gauge or piezoelectric component detects that change and produces a voltage. Calibration establishes the relationship between voltage and force, allowing biological measurements to be reported as objective force values rather than descriptive observations.
Strain gauges and piezoelectric components act as sensing elements within the measurement system. Each detects the response of the elastic element to an applied load and contributes to an electrical output that can be calibrated to force. Their inclusion allows the system to translate mechanical events, such as contraction or loading, into measurable experimental data.
Calibration makes the electrical signal interpretable as force by defining how voltage corresponds to the applied load. A proportional relationship supports consistent comparisons among measurements, conditions, or experimental treatments. Without that relationship, the recorded signal would indicate electrical change but would not provide a reliable quantitative estimate of the biological force producing it.
The system records changes in force as a biological event occurs, producing a force-time record rather than a single endpoint value. This record can characterize the timing and magnitude of mechanical activity, including muscle contraction or movement-related loading. Such patterns support analysis of physiology, motor control, locomotion, and other time-dependent biological functions.
A basic workflow applies a biological load to the transducer, permits the elastic element to respond, detects the resulting deformation, and converts the electrical output through calibration. The resulting force record can then be examined in relation to the movement, contraction, or interaction that produced it. This sequence provides objective data for biological analysis.
Applications include characterizing muscle contraction, biomechanical loading, cell-generated forces, and interactions between organisms and their environment. The same quantitative approach can support studies of tissue mechanics, locomotion, and motor control. Because measurements are objective, researchers can also examine how disease or experimental treatments affect biological force production or mechanical function.
