2025
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...

Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN Electric potential, also known as "voltage", measures the electric potential energy per unit charge. Electric field is a scalar quantity and is fundamental to many electrical effects. Like potential energy, what is physically meaningful is the difference in the electric potential. For example, the spatial variation in the electric potential is related to the electric...

Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...
FAQs
The sensing element responds to a physical quantity by changing an electrical property such as resistance, capacitance, inductance, voltage, or charge. The particular property links the measured condition to the resulting signal. For example, strain gauges, thermistors, capacitive sensors, inductive sensors, and piezoelectric devices apply different response principles to represent physical changes electrically.
Different sensing principles suit different measured quantities because they respond through different electrical properties. Resistance-based devices include strain gauges and thermistors, while capacitive and inductive sensors rely on changes in capacitance or inductance. Piezoelectric devices provide voltage or charge responses. This distinction helps engineers match a transducer type with the physical condition being monitored.
Signal-conditioning circuits prepare the sensing element’s output for reliable interpretation. Amplification increases the usefulness of a signal, filtering helps manage unwanted signal content, and conversion presents the output in a suitable form for measurement or control. These stages are important because the raw electrical response may not be directly suitable for instrumentation or automated systems.
A typical workflow begins with a physical condition such as temperature, pressure, displacement, force, or light acting on the sensing element. Its electrical property or generated voltage or charge then changes, after which signal-conditioning circuits amplify, filter, or convert the response. The conditioned signal can support measurement, process monitoring, or control decisions.
Engineers use them when systems must observe physical conditions and represent those conditions as electrical signals. In instrumentation, they support measurement of quantities such as force, pressure, or temperature. In process monitoring, their outputs help track operating conditions. Their use allows physical behavior to be incorporated into measurement systems rather than observed only directly.
Electrical transducers provide the measured-condition signals that automated systems and feedback-control arrangements require. A physical condition is sensed, represented electrically, and conditioned for interpretation by the system. This connection allows equipment to monitor its operating state and use measurement information in control processes, making transducers an important engineering link between physical conditions and system response.
