    • Architecture-independent power bound for vibration energy harvesters 

      Halvorsen, Einar; Le, Cuong Phu; Mitcheson, P.D.; Yeatman, Eric M. (Journal article; Peer reviewed, 2013)
      The maximum output power of energy harvesters driven by harmonic vibrations is well known for a range of specific harvester architectures. An architecture-independent bound based on the mechanical input-power also exists ...

    • Electric control of power extracting end-stop for MEMS vibration energy harvesting 

      Truong, Binh Duc; Le, Cuong Phu; Halvorsen, Einar (Journal article; Peer reviewed, 2014)
      This experimental work investigates a technique to further improve performance of vibration energy harvesters under displacement-constrained operation. Previously, a device concept based on end-stops acting as additional ...

    • Equivalent-circuit model for slot-effect configuration of an electret-based generator 

      Le, Cuong Phu; Renaud, Michael; Halvorsen, Einar (Journal article; Peer reviewed, 2016)
      This paper presents a completely analytical method to build a lumped-model for an electret-based energy harvester. The harvester consists of two patterned electrodes facing movable electret patterns in a slot-effect ...

    • Experimentally verified model of electrostatic energy harvester with internal impacts 

      Truong, Binh Duc; Le, Cuong Phu; Halvorsen, Einar (Journal article, 2015)
      This paper presents experimentally verified progress on modeling of MEMS electrostatic energy harvesters with internal impacts on transducing end-stops. The two-mechanical-degrees-of-freedom device dynamics are described ...

    • Experiments on power optimization for displacement-constrained operation of a vibration energy harvester 

      Truong, Binh Duc; Le, Cuong Phu; Halvorsen, Einar (Journal article; Peer reviewed, 2015)
      This paper presents experiments on how to approach the physical limits on power from vibration energy harvesting under displacement-constrained operation. A MEMS electrostatic vibration energy harvester with voltage-control ...

    • Low power electronic interface for electrostatic energy harvesters 

      Phan, Tra Nguyen; Azadmehr, Mehdi; Le, Cuong Phu; Halvorsen, Einar (Journal article; Peer reviewed, 2015)
      This paper presents design and simulation of a power electronic interface circuit for MEMS electrostatic energy harvesters. The designed circuit is applicable to highly miniaturized electrostatic harvesters with small ...

    • MEMS electrostatic influence machines 

      Le, Cuong Phu; Halvorsen, Einar (Journal article; Peer reviewed, 2016)
      This paper analyses the possibility of MEMS electrostatic influence machines using electromechanical switches like the historical predecessors did two centuries ago. We find that a generator design relying entirely on ...

    • Power optimization and effective stiffness for a vibration energy harvester with displacement constraints 

      Truong, Binh Duc; Le, Cuong Phu; Halvorsen, Einar (Journal article; Peer reviewed, 2016)
      This paper presents experiments on how to approach the physical limits on power from vibration energy harvesting under displacement-constrained operation. A MEMS electrostatic vibration energy harvester with voltage-control ...
