Piezoelectric Vibrational energy Harvesters for Powering the IoT nodes

In this project we will be working on designing linear energy harvesters that scavenge low frequency-low amplitude ambient vibrational energy using MEMS resonators. We will work on optimizing the design based on real vibrations available and increase the efficiency over existing designs.

About the Project

IoT is a booming industry with a predicted 50 billion connected devices by 2025. Such a huge number of devices would require equally large number of batteries to power them. But batteries are not a feasible solution due to several important reasons. Batteries add to e-waste, require periodic replacement and maintenance, all these are not possible for remotely located IoT nodes. Therefore, we must shift our attention to a different solution. Energy harvesters are a sought-after solution to this issue. Extracting energy from always available ambient vibrations has been a topic of interest for several years. Piezoelectric transduction is a better option over other transduction mechanism available.

In this project we will be working on designing linear energy harvesters that scavenge low frequency-low amplitude ambient vibrational energy using MEMS resonators. We will work on optimizing the design based on real vibrations available and increase the efficiency over existing designs.
