Energy Harvesting for Wearable Sensor Systems

This book investigates several non-resonant inductive harvester architectures in order to find the magnet coil arrangement that generates the largest power output. The book is useful as a step-by-step guide for readers unfamiliar with this form of energy harvesting, but who want to build their own system models to calculate the magnet motion and, from that, the power generation available for body-worn sensor systems. The detailed description of system model development will greatly facilitate experimental work with the aim of fabricating the design with the highest predicted power output. Based on the simulated optimal geometry, fabricated devices achieve an average power output of up to 43 mW during walking, an amount of power that can supply modern low-power, body-worn systems. Experiments were also carried out in industrial applications with power outputs up to 15 mW. In sum, researchers and engineers will find a step-by-step introduction to inductive harvesting and its modeling aspects for achieving optimal harvester designs in an efficient manner.

Low Power Circuits with Integrated Magnetics for Sensors and Energy Harvesting Systems

This work explores the use of integrated magnetics in microelectronics to enable low power, energy-efficient sensing, as well as energy harvesting to power the sensors, in a compact form factor.

Low Power Circuits with Integrated Magnetics for Sensors and Energy Harvesting Systems

The continued expansion of Internet of Things has led to a proliferation of wireless sensors and systems across the globe. The application space for sensors is wide-ranging: from industries, to serve the upcoming era of Industry 4.0, to consumer products, like body wearable sensors. The rise to billions of sensors relies on two key trends in sensor systems: miniaturization and energy-efficiency. This work explores the use of integrated magnetics in microelectronics to enable low power, energy-efficient sensing, as well as energy harvesting to power the sensors, in a compact form factor. For industrial applications, we present the design of a bandwidth-scalable, integrated fluxgate magnetic-to-digital converter for energy-efficient contactless current sensing in smart connectors. The system uses mixed signal front-end design to en-able duty cycling and quick convergence techniques leading to 20x reduction in power consumption at low bandwidths of 1 kHz for power monitoring. It also employs fast read-out circuits to achieve a bandwidth of 125 kHz for machine health diagnosis. For personal body wearable electronics and beyond, we present the design of a cold start system with integrated magnetics for ultra low voltage startup in thermal energy harvesting applications. The Meissner Oscillator analysis with on-chip magnetics allows co-optimization of magnetics and circuits to achieve start up from as low as 25 mV input voltage to the circuits, despite 1000x lower inductance than off-chip transformers. Given the recent push towards artificial intelligence and a growing need for data, along with sensors to collect that data, we need to explore novel uses of technologies to meet the demands for small form factor and low power operation, as the number of sensors scale. The ideas presented in this thesis, with two very different applications of the integrated magnetics technology, can contribute to the continued growth towards trillions of sensors.

Design and Implementation of Energy Harvesting Circuits for Medical Devices

Technological enhancements in a low-power CMOS process have promoted enhancement of advanced circuit design techniques for sensor related electronic circuits such as wearable and implantable sensor systems as well as wireless sensor nodes (WSNs). In these systems, the powering up the electronic circuits has remained as a major problem because battery technologies are not closely following the technological improvements in semiconductor devices and processes thus limiting the number of sensor electronics modules that can be incorporated in the design of the system. In addition, the traditional batteries can leak which can cause serious health hazards to the patients especially when using implantable sensors. As an alternative solution to prolonging the life of battery or to mitigate serious health problems that can be caused by battery, energy harvesting technique has appeared to be one of the possible solutions to supply power to the sensor electronics. As a result, this technique has been widely studied and researched in recent years. In a conventional sensor system, the accessible space for batteries is limited, which restricts the battery capacity. Therefore, energy harvesting has become an attractive solution for powering the sensor electronics. Power can be scavenged from ambient energy sources such as electromagnetic signal, wind, solar, mechanical vibration, radio frequency (RF), and thermal energy etc. Among these common ambient sources, RF and piezoelectric vibration-based energy scavenging systems have received a great deal of attention because of their ability to be integrated with sensor electronics modules and their moderate available power density. In this research, both RF and piezoelectric vibration-based energy harvesting systems have been studied and implemented in 130 nm standard CMOS process.
