Ultrasonic sensor, tactile sensor, grasping apparatus, and electronic device
An ultrasonic sensor includes: a substrate; an ultrasonic transducer disposed on the substrate, and configured and arranged to transmit ultrasonic waves that propagate as plane waves in a direction orthogonal to a surface of the substrate; an acoustic refracting part contacting the ultrasonic transducer, and configured and arranged to refract the ultrasonic waves transmitted from the ultrasonic transducer; an elastically deformable elastic portion contacting the acoustic refracting part; and an ultrasonic reflecting member disposed within the elastic portion, and configured and arranged to reflect the ultrasonic waves. The acoustic refracting part is configured and arranged to refract, toward the ultrasonic reflecting member, the ultrasonic waves transmitted from the ultrasonic transducer.
