概要
The STNFCSensor application, available for Android and I/Os, demonstrates the innovative energy harvesting capability integrated into the embedded ST25DV series dynamic NFC tag.
This feature enables the device to operate without an internal battery, harnessing energy wirelessly from an external NFC reader.
The STEVAL-SMARTAG1 development board, which runs the FP-SNS-SMARTAG1 firmware, leverages this energy harvesting functionality to power the system solely through the energy captured from the NFC field.
As a result, the device can reliably collect and transmit sensor data even in one-shot mode, where data is read once per activation, without relying on any onboard power source.
This capability is particularly advantageous for applications where battery replacement is impractical or undesirable, such as in remote sensing, asset tracking, or maintenance-free IoT devices.
By eliminating the battery, the system reduces maintenance costs, improves reliability, and supports sustainable, eco-friendly designs.
