An accelerometer based on thermoformed piezoelectrets with open-tubular channels

Ferro- or piezoelectrets (especially thermoformed multilayer systems), developed at the beginning of 2000, exhibit flexibility and high piezoelectricity as their major properties. These materials have led to significant technological advances in several applications, including sensors and transducers, such as underwater ultrasound and accelerometers. This paper introduces a new approach for the pr...
