Latest Patents

Jang's latest patents focus on methods and apparatus for acoustic backscatter communication. This communication system utilizes backscattered acoustic signals that can propagate through both liquid and solid mediums. In this system, one or more transmitters send acoustic signals that travel to and are reflected by an acoustic backscatter node. The backscatter node is capable of modulating the amplitude and/or phase of the reflected acoustic signals by varying the acoustic reflectance of a piezoelectric transducer onboard the node. The modulated signals that reflect from the backscatter node can then travel to a microphone for decoding. Additionally, the backscatter node may include sensors, allowing the uplink signals to encode sensor readings. Notably, the backscatter node can harvest energy from the downlink acoustic signals, enabling both the node and the sensors to operate without batteries. Multiple backscatter nodes can communicate concurrently at different acoustic frequencies, with each node equipped with a matching circuit that has a distinct resonant frequency.
