  • Piezoelectric Transducers for Ventilators and Nebulizers
    Piezoelectric transducers are at the heart of many a medical apparatus. Chronic respiratory diseases like mucoviscidosis, asthma or chronic obstructive pulmonary disease (COPD) but also bronchitis, influenza and lung diseases related to COVID-19 require extensive medical treatment. Medical
  • Magnetostrictive Versus Piezoelectric Transducers For Power Ultrasonic Applications
    There are two fundamental transducer designs used for power ultrasonic applications today, magnetostrictive and piezoelectric. Piezoelectric transducers utilize the piezoelectric property of a material to convert electrical energy directly into mechanical energy. Magnetostrictive transducers
  • Piezoelectric Accelerometer Design
    Information about piezoelectric accelerometer design including piezoelectric transducers, quartz and piezoceramics, mechanical design, charge amplification. and design trade-offs.
  • Analysis of Piezoelectric Devices
    Analysis of Piezoelectric Devices. Based on the linear, nonlinear, three-dimensional and lower-dimensional structural theories of electromechanical materials, this book presents results for devices such as piezoelectric resonators, acoustic wave sensors, and piezoelectric transducers.
  • Transducers and Arrays for Underwater Sound
    Transducers and Arrays for Underwater Sound. Presenting basic acoustic concepts and models needed in transducer and transducer array development, this book discusses the six major types of electroacoustic transducers and shows why piezoelectric ceramic transducers are suitable for underwater sound.
  • Controlling Sound Level- Electronic Method
    For piezoelectric type audible alarms, the larger the voltage signal applied to the piezoelectric transducer, the louder the sound level. This property can be used to electronically control the sound level of these devices.
  • Piezoelectric Measurement System Comparison: Charge Mode vs. Low Impedance Voltage Mode (LIVM)
    Piezoelectric sensors (Transducers) measure dynamic phenomena such as force, pressure and acceleration (including shock and vibration). Inside the sensor, piezoelectric materials such as quartz and man-made ceramics are stressed in a controlled fashion by the input measurand i.e., the specific
  • Audible Alarm Use and Equipment Integrity Challenges
    The most common type of electronic audible alarm utilizes a piezoelectric transducer. The transducer consists of a metal disc with an attached ceramic material that flexes when voltage is applied. By applying a complex signal to the transducer such as a sine wave, an audible sound is generated
