Presentation Summary

With the advent of the Internet of Things the need for autonomous wireless sensor systems has gained traction. Vibration energy harvesting has been presented as a key element to achieve such an objective. However, such a solution needs to be cost-effective to the consumer market, and topologies need to address unique application environments. Exploiting additive manufacturing techniques (3D printing) will help achieve such an objective as: they are currently more cost effective on the small to medium scale (in comparison to traditional subtractive methods); can manufacture complex topologies monolithically (eliminating complex assembly requirements); and offer designers a rapid method of design iteration, enabling them to provide solutions for unique environments quickly and cheaply.
The presentation will outline some of Tyndall's activities in the development of novel 3D printed vibration energy harvesters designed to harness vibrations acting 'in-plane' to the device. In addition, a brief overview of Tyndall's progress in developing vibration energy harvesters will be presented. Systems utilizing cheap materials such as FR-4, as well as systems developed for batch Silicon fabrication processes, which would be suitable for non-intrusive applications, will be outlined briefly. Furthermore, advances in the methods of electrical tuning and optimal high energy branch operation will be presented.
