Kiziroglou ME, Yeatman EM, 2012, 17 - Materials and techniques for energy harvesting, Functional Materials for Sustainable Energy Applications, Editors: Kilner, Skinner, Irvine, Edwards, Publisher: Woodhead Publishing, Pages: 541-572, ISBN: 978-0-85709-059-1

Abstract: Energy harvesting, the collection of small amounts of ambient energy to power wireless devices, is a very promising technology for applications where batteries are impractical, such as body sensor networks and inaccessible remote systems. The performance and potential of energy-harvesting devices depend strongly on the performance and specific properties of materials. In this chapter the important properties and potential of materials used in energy-harvesting devices are reviewed. An introduction to the concept of energy harvesting is given with a special discussion on motion energy-harvesting limits. The state of the art of materials for piezoelectric, electrostatic, thermoelectric and electromagnetic harvesting devices is discussed, with emphasis on desired material properties and corresponding available materials. In addition to the materials required in the energy transduction mechanism itself, the performance of mechanical oscillators at small scales is a critical factor in motion energy harvesting. For this reason, material requirements, performance and limitations for the implementation of low-frequency and broadband mechanical oscillators are reviewed in the final section of this chapter.

He C, Arora A, Kiziroglou ME, Yates DC, O'Hare D, Yeatman EMet al., 2009, MEMS energy harvesting powered wireless biometric sensor, Pages: 207-212

One of the main challenges in developing wireless biometric sensors is the requirement for integration of various systems into a very compact device. Such systems include sensing units, conditioning electronics, transmitters and power supplies. In this work, a novel system integration architecture is presented. A unique feature of this new architecture is that the sub-systems are selected and designed for direct output-to-input connection. An array of active pH sensors is used to transform a pH level to an electrical potential in the range of 0-2 Volts. This signal is amplified by an electrostatic energy harvester suitable for human motion operation. The amplified signal drives a custom LC transmitter specially designed to suit the harvester output. A system of notable simplicity is achieved and may serve as a demonstrator for other wireless sensors. © 2009 IEEE.

The difficulty of maximizing the proof mass, and lack of broadband operation, are key issues for miniaturized energy-harvesting devices. Here, a novel electrostatic energy harvester is presented, employing an external free-rolling proof mass to address these issues. A description of the operating principle is given, and the kinetic dynamics of the cylinder are analyzed. The electrostatics of the system are simulated, identifying the device performance for different dielectric dimensions and surface specifications. The fabrication of a prototype device is presented, and physical characterization results demonstrate a successful fabrication technique for dielectric sizes down to 100 nm. Capacitance measurements reveal a capacitance ratio of 4 and are in agreement with simulation results. A voltage gain of 2.4 is demonstrated. The device is suitable for energy harvesting from low-frequency high-amplitude ambient motion sources such as the human body.

The quality factor (Q) of integrated inductors is of great importance to radio frequency applications. Monolithic integration of out-of-plane Au inductors with Complementary Metal-Oxide-Semiconductor (CMOS) LC oscillators is reported in this paper. The recently developed self-assembly process involves in-plane fabrication of Au inductors and subsequent rotation of the structure by surface tension forces of a melting Sn hinge. The CMOS compatibility of this process is demonstrated through the integration of an LC oscillator with the self-assembled inductor using post-CMOS processing. At a 1.48 GHz oscillation frequency, a phase noise of -95 dBc/Hz is reported at a 100 kHz frequency offset. Obtained results show this technique to be promising for the integration of high Q inductors with commercial RF systems.
