Latest Patents

One of his latest patents is titled "Reduced graphene oxide film comprising a stack of rGO layers and its applications." This invention relates to a reduced graphene oxide (rGO) film with a total thickness ranging from 20 nm to 5 micrometers. The film comprises a stack of rGO layers with flakes, where the distance between two consecutive layers is between 0.2 to 0.7 nm. It also includes an electrically back-contacted conductive rGO structure, which is deposited on an additional conductive support. This invention is crucial for the preparation of rGO films and electronic devices that can detect, receive, and induce electrical signals.

Another significant patent is "Circuit for the multiplexing and read-out of variable-resistance sensor arrays." This invention proposes an apparatus and method for multiplexing and reading arrays of sensors without using switching elements. The sensor elements are organized in groups and columns, with each column receiving a continuous voltage waveform of varying amplitude, frequency, and phase characteristics. This setup allows for the modulation of current signals by the variable resistance signals to be measured. The read-out circuits then demultiplex each individual sensor signal through lock-in demodulation.
