As a promising solution, energy harvesting technique that scavenges power from ambient sources such as light, heat or vibration has been widely researched in recent years.

Following, we presented a two-stage low-input boost converter as a thermoelectric energy harvesting interface in Chapter 3. With low threshold voltage MOS transistors and the design guideline we proposed, the boost converter is able to boost a 0.11V voltage up to a level above 1V with extra assistance. The last work in this thesis is a thermo-powered wireless ECG monitoring system with arrhythmia detection circuit, which is a highly integrated biomedical system that shows the integration potential of the energy harvesting interface. All the works are fabricated in TSMC 0.18μm 1P6M process. 呂學士 2013 學位論文 ; thesis 115 en_US |

碩士 === 國立臺灣大學 === 電子工程學研究所 === 101 === Owing to the shrink of biomedical electronic devices, the space permitted for battery is getting smaller and smaller, which results in the shortening of the device lifetime. As a promising solution, energy harvesting technique that scavenges power from ambient sources such as light, heat or vibration has been widely researched in recent years. Being renewable and inexhaustible, energy harvesting seems to be the best cure for the powering disease of the implant biomedical devices.
To begin with, a high efficiency piezoelectric energy harvesting interface is reported. With a company of an inductor and switches, the full-bridge rectifier can achieve a higher power extracting efficiency. The control overhead is much less than one micro watt.
Following, we presented a two-stage low-input boost converter as a thermoelectric energy harvesting interface in Chapter 3. With low threshold voltage MOS transistors and the design guideline we proposed, the boost converter is able to boost a 0.11V voltage up to a level above 1V with extra assistance.
The last work in this thesis is a thermo-powered wireless ECG monitoring system with arrhythmia detection circuit, which is a highly integrated biomedical system that shows the integration potential of the energy harvesting interface.
All the works are fabricated in TSMC 0.18μm 1P6M process.
