Piezoelectric film can replace the traditional elements and transmit vital signs to detect signal to the medical monitoring system

Dynamic piezoelectric thin film strain gauge characteristics piezoelectric film can easily be fixed directly on the human skin ( eg inside of your wrist ) . Filters collected . Similar sensors have been used in the detection of sleep disorders chest, legs , the movement of the eye muscles and skin . In addition , the sensor can detect the muscle ( e.g. muscle between the thumb and forefinger ) as a test of the shock reaction anesthesia indicator ( neuromuscular transmission ) . Acceleration sensor Minisense100 is a standard precision electronic products , the use of cantilever design, clamped at one end with rigid PCB board and en pin and the other end with the mass . Mass when Automobile Temperature Sensor is subjected to vibration in a coherent response. Mass ' remain stationary ,' and the film portion is deformed , resulting in a very high voltage sensitivity (about 1V / g). This component derived from the other vital signs sensors, such as staff or patient wearing a smart badge ( built-in RF telemetry equipment ) . Collected by the wearer phased signals to determine its location and track its status. Sensor senses the badge will be off when the badge is set to the sleep state ; if the sensor to feel the movement of any part of the body , muscle tremors , or of the pulse vibrations , will wake badge. Auscultation
Many electronic stethoscopes are used as Crank Position Sensor element of the piezoelectric film , because it is durable , high sensitivity and wide bandwidth . In this application, the sensor elements are usually packaged in conventional metal auscultation head , because the sensor is formed with the body to ' force ' . Once the dynamic pressure signals into electrical signals , can be selectively filtering or amplification , as the audio signal playback , the use of more sophisticated calculation method to determine the specific position , or transmitted to a remote station for further analysis and storage. Care beds piezoelectric film and the piezoelectric cable can be installed on the mattress detect the patient's heart rate, breathing and body movements. Hoana Medical Inc. Guardianship bed alarm system installed between the mattress and sheets a set of sensors. Patient sitting or lying in bed guardianship , Crankshaft Positioning Sensor can accurately measure across the clothes and blankets collected information on the patient's vital signs . Soft switch is used to capture a static signal , the patient all dynamic signals collected by the piezoelectric film and converted into corresponding electrical signals , display side of the bed . The patient's heart rate and respiration rate is not normal, or the patient out of bed without permission , the system can advance warning . All this completed by the sensor without having direct contact with patients . Respiratory monitoring the piezoelectric thin film manufacturing thermoelectric lips touch sensor using the same principle , the detection of air through the mouth or nose . With respect to the thermistor , the piezoelectric film with high sensitivity , fast response , flexibility , and the probe area . Conclusion seen from the above application case , the piezoelectric film can be an alternative to traditional elements and transmit vital signs to detect signal to the medical monitoring system . I believe that in the near future, the piezoelectric film by virtue of its many advantages, more widely used in the treatment and care of .
