Abstract
Described herein are bio-inspired acoustic bandpass sensors with a user-defined range of frequencies mimicking the geometric structure of a human's basilar membrane to capture infrasonic, sonic or ultrasonic waves per design with a target frequency range for a specific application and methods of making same.
Claims20
A bioinspired acoustic bandpass sensor comprising:
- at least one sensor array defining a geometric structure formed to mimic a basilar membrane of a subject;
- the geometric structure comprising:
- at least one electrode fabricated on opposite surfaces of a piezoelectric continuum;
- and
- the piezoelectric continuum comprising a trapezoidal geometry atop an elastomer matrix defining at least one embedded electrode groove to contain the at least one electrode and a duct.
