  • Thin-film-integrated power inductor on Si and its performance in an 8-MHz buck converter 
    Wang, Ningning; O'Donnell, Terence; Meere, Ronan; Rhen, Fernando M. F.; Ó Mathúna, S. Cian; Roy, Saibal (Institute of Electrical and Electronics Engineers, 2008-11)
    This paper presents a microinductor fabricated on silicon using electrochemical techniques that has high efficiency in a low power dc–dc converter. Small signal measurements show a flat frequency response up to 20 MHz with ...
  • Design considerations of sub-mW indoor light energy harvesting for wireless sensor systems 
    Wang, Wensi S.; O'Donnell, Terence; Wang, Ningning; Hayes, Michael; O'Flynn, Brendan; Ó Mathúna, S. Cian (ACM, 2010-06)
    For most wireless sensor networks, one common and major bottleneck is the limited battery lifetime. The frequent maintenance efforts associated with battery replacement significantly increase the system operational and ...
  • DC/DC converter 3D assembly for autonomous sensor nodes 
    Hilt, Thierry; Boutry, Herve; Franiatte, Remi; Rothan, Frederic; Sillon, Nicolas; Stam, Frank; Mathewson, Alan; Wang, Ningning; Ó Mathúna, S. Cian; Rodgers, Kenneth (IEEE, 2010-06-04)
    This paper reports on the design and the manufacturing of an integrated DCDC converter, which respects the specificity of sensor node network: compactness, high efficiency in acquisition and transmission modes, and ...
  • Bulk material based thermoelectric energy harvesting for wireless sensor applications 
    Wang, Wensi S.; Magnin, Wassim; Wang, Ningning; Hayes, Michael; O'Flynn, Brendan; Ó Mathúna, S. Cian (IOP Publishing Ltd,, 2011)
    The trend towards smart building and modern manufacturing demands ubiquitous sensing in the foreseeable future. Self-powered Wireless sensor networks (WSNs) are essential for such applications. This paper describes bulk ...
  • Hybrid energy storage for energy harvesting powered wireless sensor networks 
    Wang, Wensi S.; Wang, Ningning; Hayes, Michael; O'Flynn, Brendan; Ó Mathúna, S. Cian (VDE VERLAG GMBH, 2011-03)
