Short summary:
Talk about the design of low-power electronic circuits that do not require a battery.
Summary
The 20th century has been the birth date of many achievements that could provide the people with higher quality services. Certainly these achievements could not be done without the emergence of the electronic field that has the transistor devices as its main parts. With these devices the electrical energy is used to provide applications that have long been sought by the people.
At the end of the last century the electronic designers have been faced by new demands that forced them to follow the state of art designs to be able to address these necessities. Mobile communication, biomedical implanting, remote sensing and outdoor Internet of Things (IoT) are typical examples of these kinds. In all of these applications having the access to the network supply is either very unlikely or not possible. Nearly all of them suffer from power, space and weight constraints and are normally battery powered with restricted supply life that needs to be recharged or renewed. But this process is not always easy and can be aggressive in biomedical implantations. Extending the life of the batteries, although seems to be a solution for the problem, can only postpone the problem for the case of the patients having a pace maker inside their body and adds to their nightmare of having an operations in the old ages. So, providing electronic circuits that could deal with these new demands is the challenge faced by electronic designers.
There have been two main approaches to address the constraints involved in these applications. Some designers tried to provide designs that consume very low or better to say ultra low power. To do so, they focused either on devices that have a low power consumption nature or on methods to lower the static power consumptions. Others have concentrated on providing or harvesting power from the neglected available sources of power in our environment (like solar and wind energies) or the bi-product of traditional sources of energy (like heat or sound) that are normally considered as waste. There is also an emerging approach that benefits from both of techniques to provide more reliability. In this presentation we try to focus on the following issues:
- An Introduction to justify the need to follow self supplied-low power design for the related applications.
- The approaches followed by the designers to address the constraints involved in these applications.
- The way the designers provide low power circuits.
- Sources of available neglected power sources and their effectiveness.
- The concept of energy harvesting.
- Introducing feasible electronic energy harvesters.
- Providing circuit examples that benefit both low power designs and energy harvesters.
