Low-cost, "zero" power displays are currently non-existent in the market. Additionally, low-cost IoT-enabled sensors with displays are also non-existent.  We have developed a low-cost and battery-less display, now available for retail electronic shelf labels. We have also developed an asset-tracking tag technology that can incorporate a wide range of sensors. By combining these three pieces of technology (display, asset-tracking tag, and sensors), we are able to provide an IoT product like none other: an IoT sensor tag incorporating a "zero" power display showing both the data collected by the sensor along with critical information about the sensor (e.g., battery level, sensor status, connectivity, etc.).
