Bernoulli gripper

 Bernoulli griper uses airflow to adhere to an object without physical contact.Such grippers rely on the Bernoulli airflow principle. While an accelerating, increasing speed, airstream has a low downstream static pressure, the sharp turn from linear to radial flow is the cause of a region of very low pressure around the blower exit hole. This is the cause of a net force on the object in the direction normal to the side with higher local pressure. A Bernoulli gripper takes advantage of this by maintaining this negative pressure at the gripper face compared to the ambient pressure below the sample, while maintaining an air gap between the gripper and the object being held.
