Abstract:
With the development of the Internet of Things (IoT) technology, a large number of wireless devices are deployed in our surroundings. The power supply issue of these IoT devices has become increasingly noteworthy. The installation and maintenance of a large number of widely distributed sensors are cumbersome. In this talk, we introduce a battery-free wireless floor tile design based on piezoelectric energy harvesting (PEH). Although there were many similar PEH floor tile designs previously built with the same low-cost piezoelectric buzzers, this design is the most compact and inclusive, as a self-powered Bluetooth beacon module. Compared to many energy harvesting floor tile designs, this one has another benefit of a small stroke distance, less than 1 mm, which brings little discomfort to natural walking. Given its motion-powering feature, the power-supply issue, easy deployment, and maintenance issues are all solved. Such smart pavement has the potential to further provide useful information about pedestrians, such as crowdedness, individual tracking, and fall detection.
