Sensors are among the mostly frequently cited additions to connectivity in the IoT and certainly are one of the key enablers for wearable products of all sorts. However, wirelessly connected sensors pose a major problem when considering batteries as the sole source of power - battery life. Converting the available energy from a variety of sources to electricity, or energy harvesting, provides an alternative to frequently changing batteries in wireless sensing applications. Popular techniques to harvest energy for sensing applications include photovoltaic, thermoelectric, piezoelectric, electrodynamic and even wind.
While energy harvesting is not a solution for every wireless sensing node, it is being successfully applied in industrial, consumer and other applications. In some instances, it is being used in conjunction with advanced battery technologies including thin-film batteries. In all cases, efficient power management is essential. As in most system problems, there are technical and cost constraints. This Webinar will provide a Sneak Preview of the in-depth Pre-Conference Symposium that will take place at Sensors Expo & Conference this June 27. Get a sneak peek at the challenges and solutions of using energy harvesting techniques of varying types for powering sensors in wireless and other ultralow power applications.
