Patent number: 10804038Abstract: The invention provides an electric circuit device including a conductive element configured to provide an electrical input to an electrical component, the resistivity of the conductive element being variable based at least on the extent of deformation thereof, and a deformable body coupled directly or indirectly to, or integral with, the conductive element such that deformation of the body causes the conductive element to deform, thereby varying the resistance thereof and altering the input to the electrical component. Said devices may be used singularly or in combination as logic elements within electrical circuits, providing drive and/or control functionality. Particular embodiments provide improved electrostatic generators.Type: GrantFiled: February 18, 2011Date of Patent: October 13, 2020Assignee: Auckland UniServices LimitedInventors: Benjamin Marc O'Brien, Iain Alexander Anderson, Thomas Gregory McKay, Emilio Patricio Calius

Patent number: 10250166Abstract: The invention relates to transformers. More particularly, the invention relates to transformers using (preferably electrostatic and more preferably dielectric elastomer) transducers such as generators and actuators. The invention further provides a priming circuit therefor.Type: GrantFiled: July 7, 2010Date of Patent: April 2, 2019Assignee: Auckland UniServices LimitedInventors: Iain Alexander Anderson, Thomas Gregory McKay, Benjamin Marc O'Brien, Emilio Patricio Calius

Patent number: 8860336Abstract: A system and method is provided for determining the capacitance between electrodes of an artificial muscle or dielectric elastomer actuator (DEA). The method comprises measuring the voltage difference between the electrodes of the DEA, the first derivative of that voltage with respect to time, and the total instantaneous current through the DEA, then calculating the capacitance of the DEA as the difference between the total instantaneous current through the DEA and the product of the voltage between the electrodes and an error term, divided by the first derivative of the voltage between the electrodes with respect to time. The capacitance may then be used to derive estimates of the leakage current, charge upon the DEA, and/or the physical state of the DEA, thereby implementing self-sensing to allow closed-loop feedback control of DEA actuation.Type: GrantFiled: February 18, 2010Date of Patent: October 14, 2014Assignee: Auckland UniServices LimitedInventors: Iain Alexander Anderson, Emilio Patricio Calius, Todd Alan Gisby, Benjamin Marc O'Brien, Shane Xie

Patent number: 8638024Abstract: The invention provides an actuator for an electric motor and an electric motor including said actuator. The actuator includes one or more body formed from a dielectric elastomer, each body having at least one active region that is directly or indirectly coupled to a drive means. The active regions are arranged such that, in use, actuation thereof causes driven means to move with components in at least first and second directions, preferably within a plane of the body.Type: GrantFiled: February 27, 2009Date of Patent: January 28, 2014Assignee: Auckland UniServices, LimitedInventors: Iain Alexander Anderson, Benjamin Marc O'Brien, Thomas Gregory McKay, Todd Alan Gisby, Emilio Patricio Calius, Scott Hayden Walbran, Thomas Swithun Hale

Publication number: 20120056509Abstract: An array of actuators is provided which is adapted for sequential actuation by way of mechano-sensitivity propagating actuation through the array, triggering each actuator upon deformation thereof caused by an adjacent actuator or a load in the form of a fluid or a solid object. Actuation is thus coordinated with minimal computational overhead. Also provided is an actuator suitable for use in such an array, a method of controlling an actuator, and a method of controlling an array of mechano-sensitive actuators.Type: ApplicationFiled: February 1, 2010Publication date: March 8, 2012Applicant: AUCKLAND UNISERVICES LIMITEDInventors: Iain Alexander Anderson, Emilio Patricio Calius, Todd Alan Gisby, Benjamin Marc O'Brien, Shane Xie
