Piezo (PVDF polymer) film is a lightweight and flexible transducer material that offers very high sensitivity to dynamic strain. Since the dynamic range and operating bandwidth of the material are extremely wide, transducers based on piezo film can offer signals uniquely rich in information content. Piezo film sensors can be used to detect body presence and movement, heart and lung sounds, pulse and respiratory rate, instructed and involuntary muscle activity, sleep monitoring, and more – all without consuming power. This talk will illustrate many of these human body contact applications with example signal data.
Richard Brown began working with sensors and actuators just as piezo film was first becoming commercialized in 1984 and has remained focused on applications of transducer technology throughout his career. The field of health and wellness is expanding rapidly beyond purely medical with strong interest from automotive and consumer markets. Richard provides applications support within the EMEA region for a range of TE Sensor Solutions product lines, including piezo film, vibration, force/torque, ultrasonic and optoelectronic components.
