Document Type and Number:
WIPO Patent Application WO/2021/189861
Kind Code:
A1
Abstract:
Provided is an ultrasonic sensor (100), comprising a sensing array (110), wherein the sensing array (110) comprises multiple sensing units (210) arranged in an array, with each of the multiple sensing units (210) comprising a first ultrasonic transducer (211) and a second ultrasonic transducer (212), respectively; the first ultrasonic transducer (211) is used for emitting a sensed ultrasonic wave; the second ultrasonic transducer (212) is used for receiving a reflected ultrasonic wave corresponding to the ultrasonic wave; the first ultrasonic transducer (211) and the second ultrasonic transducer (212) are arranged in parallel on a plane; and the first ultrasonic transducer (211) and the second ultrasonic transducer (212) have the same central shaft (210C), which is perpendicular to the plane.
