摘要： A device (100) and method for adhering by suction to a target surface (200). The device has a substrate (20) with a contact surface (20a) for contacting the device (100) to the target surface (200). A plurality of pocket (10) are formed by respective pocket surfaces (10a) concavely extending into the contact surface (20a). The pockets (10) have an open side (10b) facing and being closed off by the target surface (200). A flexible membrane (15) forms at least part of the pocket surface (10a). An actuator (40) is configured to actuate the flexible membrane (15). A one-way valve (30) through the pocket surface (10a) is configured to direct a contents of the pocket (10) via the one-way valve (30) to an environment (300).

摘要： An acoustic device (100) comprises an array of acoustic transducers (10a,10b) formed by a patterned stack (12-15) on a flexible substrate (11). The stack comprises a piezoelectric layer (13) sandwiched between respective bottom and top electrode layers (12,15), and a patterned insulation layer (14) formed by a pattern of insulation material (14m). The pattern comprises insulated areas (A14) where the insulation material (14m) is disposed between one of the electrodes (12,15) and the piezoelectric layer (13), and contact areas (A10) without the insulation material (14m) where both electrodes (12,15) contact the piezoelectric layer (13).
