Abstract
A non-contact handling tool for picking up an object, the tool comprising an ultrasonic transducer extending between a reflective side and a picking side configured to emit ultrasounds forming, in a near field area of the picking side, an excess-pressure wave, and a fluid suction system configured to suction a fluid towards the picking side, forming in said near field area an under-pressure. The fluid suction system comprises at least a fluid suction channel disposed in the ultrasonic transducer. The transducer has a height defined between the picking side and the reflective side corresponding to a half wavelength of the ultrasounds generated in the transducer.
