Ultrasonic Fetal Heart Rate Transducer Sheet is a high-precision device for detecting the heart rate of the fetus in the womb of a pregnant woman, working mainly through ultrasonic technology. The accurate detection of fetal heartbeat is achieved by converting ultrasonic signals into electrical signals or electrical signals into ultrasonic signals through piezoelectric transducer sheets. These transducer sheets are usually made of piezoelectric materials with high sensitivity and stability, enabling real-time monitoring of fetal heart rate changes under non-invasive conditions. Ultrasonic sensors calculate the heartbeat frequency by sending high-frequency sound waves and receiving an echo signal. This sensor sheet is widely used in fetal heart rate monitors, pregnancy health monitoring, and other applications.
Ultrasonic cosmetic wafers and transducers are made of piezoelectric ceramics and their principle of operation is based on the piezoelectric effect, whereby ultrasonic waves are generated by applying a voltage that causes the material to vibrate. Ultrasonic transducers are designed with precision and material selection to ensure that they are capable of emitting ultrasound waves of specific frequencies and intensities to meet the needs of different applications. Ultrasonic transducers also have good durability and reliability to maintain stable performance over long periods of time. With high sensitivity and stability, it can respond quickly to acoustic signals in different media. Made of high-quality materials with good abrasion and corrosion resistance. Ultrasonic transducer wafers are well-designed, easy to install and maintain, and can be widely used in ultrasonic cleaning, ultrasonic welding, ultrasonic ranging, and other fields.
Piezoelectric ceramics are a kind of functional material that can convert mechanical and electrical energy into each other. When subjected to mechanical pressure, they will produce an electric charge, a phenomenon known as the positive piezoelectric effect; when an electric field is applied, they will deform, a phenomenon known as the reverse piezoelectric effect.
Piezoelectric ceramics are widely used in sensors, actuators, ultrasonic generators, energy harvesters, and other fields. For example, sensors, can detect small pressure changes and convert them into electrical signals; in actuators, they can convert electrical signals into precise mechanical movements. Due to their unique physical properties, piezoelectric ceramics play an important role in precision control and high-accuracy measurement equipment. Ultrasonic piezoelectric ceramics have high sensitivity and stability, and can efficiently convert electrical energy into acoustic and kinetic energy, which is widely used in medical imaging, non-destructive testing, distance measurement, and other fields.
