Abstract
An adhesive apparatus with an electrostatic adhesive including a microstructured adhesive disposed over an electrode and/or a piezoelectric element. The adhesive can be added to any robotic gripper, such as a gripper finger formed of a flexible material and including a grip surface. The electrode and/or a piezoelectric element can be used for applying an electrostatic field and/or ultrasonic vibration, configured for cleaning the microstructured adhesive, releasing the adhesive, and/or sensing a load on the adhesive apparatus.
