Piezo Sensor Applications Piezo sensors are used within many sensors and devices. They are used to convert a physical parameter; for example acceleration or pressure, into an electrical signal. Piezo sensors are used to measure the change in pressure, acceleration or strain by converting them into electrical charge. They offer very high sensitivity which makes them very well suited to applications within patient monitoring. Piezo Sensor Applications Piezo sensors are used for many applications, some of them are within everyday objects. For example; Intruder alarms PIN pads Medical devices Key fobs Alarm Clocks Fire alarms Carbon monoxide detectors Microwave ovens Ultrasonic pet training collars Ultrasound equipment Within microphones Piezo Sensors within the Medical Industry Piezo sensors are well used within the medical industry, they are often used for the following; Pulse measurement - they are sensitive enough to record pulse measurements and can be bonded to the patients body with self-adhesive. Stethoscopes - because of their high sensitivity and robustness piezo sensors are often used within stethoscopes. Anaesthesia Effectiveness - piezo sensors are used to measure the effectiveness of anaesthesia as they measure the response of muscles to electrical stimulation. Sleep Studies - piezo sensors are used to measure the movements of patients during sleep studies. They can be attached to various parts of the body and will give a reading even if the smallest movement is detected. Pacemakers - Piezo sensors are used within pacemakers to detect the level of physical activity meaning the pacemaker can be adjusted where needed.
