Sensors Expo 2018: Sensors Everywhere, How Do You Power Them? | Sensors Magazine
Okay, so the stats say there will be over 10 trillion sensors deployed across the internet soon. The exact date varies from statistician to statistician, but rest assured, it will happen… . . . soon. Now you may ask, where is all the power for those little devices going to come from? In most cases, conventional batteries, regardless of how long they last are not always an ideal solution, particularly in adverse environments where replacing them can be costly in more terms than money.
Energy harvesting, in concept and reality has been around for a while, going in and out of popularity, yet always getting a nod as the most plausible solution for remote deployments of many sensors and other devices. That’s simply because it makes good sense: generate, not supply, the necessary power at the point of deployment. However, great strides are being made in battery technology that show promise in the vast IoT frontier.
Sensors Expo & Conference 2018 in San Jose, CA, will be offering a session dedicated to presenting more than a few strategies for powering those autonomous internet of things (IoT) sensors. On Wednesday, June 27, from 10:00 am to 10:50 am, it will be more than worth the time to attend the session titled, “Review of Energy Harvesting and Energy Storage Sources for Autonomous IoT Sensing Devices”, presented by Dr. Louise Turner from Ilika Technologies. As the number of IoT sensors soars, the need for small, long-life low-maintenance, and high-energy power sources escalates. Dr. Turner’s session will review challenges and opportunities in powering sensing devices by comparing combined energy harvesting sources, energy storage devices, and charging methods in use cases ranging across medical, automotive, industrial, agriculture IoT, and Smart Homes and Smart Cities.
