Here, we experimentally compare singly curved and straight piezoelectric transducers embedded in reinforced concrete structures for energy harvesting and structural health monitoring by evaluating their open-circuit voltage, power generation, power storage, and damage detection capability. Curved transducers have surpassed the straight ones, offering better performance for real-world applications.

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...

Source: Laboratory of Dr. B. Jill Venton - University of Virginia Calibration curves are used to understand the instrumental response to an analyte and predict the concentration in an unknown sample. Generally, a set of standard samples are made at various concentrations with a range than includes the unknown of interest and the instrumental response at each concentration is recorded. For more accuracy and to understand the error, the response at each concentration can be repeated so an error...

Heating and Cooling Curves

When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves. For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...
FAQs
The shaped geometry changes how vibrations travel from the piezoelectric material into a target surface or surrounding medium. Depending on its form, the transducer can direct acoustic energy, focus it, or improve vibrational matching with a curved structure. This geometric control helps engineers concentrate energy or receive mechanical responses more effectively than an unadapted interface.
An alternating voltage repeatedly drives expansion and contraction in the piezoelectric material, producing controlled mechanical vibrations. The resulting motion can be directed toward a selected surface or medium by the transducer’s curvature. This relationship between electrical input and mechanical output allows engineers to control when and where acoustic energy is delivered.
A conformal shape can follow the contour of a curved structure, helping the transducer match the surface rather than contacting it through a poorly suited flat interface. Better geometric matching supports more effective transmission or detection of vibrations. In compact engineering systems, this feature can improve integration while preserving controlled acoustic or mechanical measurements.
Engineers first position the shaped transducer so its curved surface matches the target structure or medium. They then apply an alternating electrical signal when mechanical excitation is needed, or monitor the electrical response when detecting mechanical motion. The resulting vibrations or signals can be analyzed for imaging, measurement, monitoring, or actuation.
Curved piezo transducers support ultrasonic imaging and nondestructive testing when controlled acoustic energy or mechanical sensing is required. They also serve distance measurement and flow monitoring systems, where the transducer interacts with a target or medium and provides an electrical or mechanical response. Their shaped geometry is especially relevant when compact, surface-matched designs are advantageous.
Depending on how the device is operated, engineers can obtain information about a target through ultrasonic imaging, evaluate structures during nondestructive testing, estimate distance, or monitor flow. The transducer may also provide controlled mechanical motion for precision actuation. These outcomes connect electrical signals and mechanical behavior to practical measurements or system control.
