  • Publication number: 20190239805
    Abstract: The present application describes embodiments of a radio-frequency identification (RFID) sensor based on a combination of a surface acoustic wave (SAW) transducer and two-dimensional electron gas (2DEG) or two-dimensional hole gas (2DHG) conducting structure, and its use in hemodynamic wearable devices. The SAW RFID sensor chip contains a piezoelectric substrate, on which a multilayer heterojunction structure is deposited. The heterojunction structure comprises at least two layers, a buffer layer and a barrier layer, wherein the layers are grown from III-V single-crystalline or polycrystalline semi-conductor materials, such as Ga N/Al Ga N. Interdigitated transducers (IDTs) transducing SAWs are installed on top of the barrier layer. A 2DEG or 2DHG conducting channel is formed at the interface between the buffer and barrier layers and provides electron or hole current in the system between the non-ohmic (capacitively-coupled) source and drain contacts connected to the formed channel.
