The ST25DV has an energy harvesting output pin, on which different resistor values where applied. Meanwhile the field was observed with a simple loop antenna and an oscilloscope. The smartphone was attached directly on the ST25 board, making sure the 2 coils are coupled in an optimal way. The receiver/harvester is the MAX66242 and its data sheet states that the device needs about 2 mA at about 3 volts, that's a power of 6 mW. For inductive power transfer, access, control, and information exchange to a 1-Wire ® network, you can take advantage of a near-field communications (NFC) system. With harvested power from the NFC link, temperature sensing, authentication, and memory storage can be accomplished via a single node for 1-Wire communication.NFC Power Harvesting is appropriate for space-constrained devices, allowing product developers to harness the small amount of power required to send over the data authentication, and utilize it for other functions with the ultimate goal of eliminating batteries.
The transmitter has selectable output-power levels of 100 mW (+20 dBm) or 200 mW (+23 dBm) equivalent into a 50 Ω load when using a 5 V supply and supports OOK and ASK modulation with selectable modulation depth. Near Field Communication (NFC) technology is extensively used for wireless power transfer, where devices communicate through inductive coupling via induced magnetic fields between transmit and receive coils (loop antennas).
First: There are two things you have to solve: Emitting enough energy from the antenna to power the chip and increasing the sensitivity of the reader receiver side, so you can read the tag response. For the first it involves getting the .TI’s TRF7964A is a TRF7964A Multi Protocol Fully Integrated 13.56-MHz NFC / RFID Reader/Writer IC. Find parameters, ordering and quality information.•Reduces harmonics of the RFO output stage •Target Cutoff Frequency about 13.56Mhz •Matching Serial Cap •Impedance match from EMC filter to antenna resonator circuit •Cuts DC path from RFO1 to RFO2 18Make your system smarter and user-friendly with the ST25R100 and ST25R200 NFC readers, offering unparalleled reading performance. Designed for seamless integration into systems with compact antennas, these readers include advanced low power card detection (LPCD) technology.
