Power-Efficient Hybrid Energy Harvesting System for Harnessing Ambient Vibrations Chamanian, Salar; Çiftci, Berkay; Ulusan, Hasan; Muhtaroglu, Ali; Külah, Haluk (Institute of Electrical and Electronics Engineers (IEEE), 2019-07-01) This paper presents an efficient hybrid energy harvesting interface to synergistically scavenge power from electromagnetic (EM) and piezoelectric (PE) sources, and drive a single load. The EM harvester output is rectified ...
Low-Cost Fully Autonomous Piezoelectric Energy Harvesting Interface Circuit with up to 6.14x Power Capacity Gain Çiftci, Berkay; Ulusan, Hasan; Yigit, Halil Andac; Koyuncuoglu, Aziz; Muhtaroglu, Ali; Külah, Haluk (2019-01-01) This paper presents a novel self-powered and fully autonomous interface circuit to extract piezoelectric energy from vibrations available in the environment for supplying DC voltage to electronic loads. A new energy extrac...
A Pulse-Width Modulated Cochlear Implant Interface Electronics with 513 mu W Power Consumption Yigit, Halil Andac; Ulusan, Hasan; Yüksel, Muhammed Berat; Chamanian, Salar; Çiftci, Berkay; Koyuncuoglu, Aziz; Muhtarolu, Ali; Külah, Haluk (2019-01-01) The fully implantable cochlear implant (FICI) interface circuit proposed in this work senses sound harmonics from 8 different piezoelectric cantilever sensors, and generates pulse width modulated biphasic current outputs t...
