  • Patent number: 11917830
    Abstract: A NAND ferroelectric memory cell with a three-dimensional structure and a preparation method thereof are provided, the ferroelectric memory cell comprises: an oxide insulating layer, a channel layer, a channel buffer layer, a ferroelectric layer, and/or a gate buffer layer, and a gate arranged successively from the inside to the outside. In the memory cell of the present disclosure, the buffer layer has the following effects: 1. It can induce the crystallization of ferroelectric film to form ferroelectric phase; 2. It can reduce adverse effects caused by different crystalline characteristics of the channel layer and the ferroelectric layer, improve the quality and uniformity of the deposited film; 3. It can enhance the interface property of the channel layer, reduce leakage current, and enhance endurance of the device. Therefore, the buffer layer can improve the overall storage property and homogeneity of memory cells with a three-dimensional structure.

  • Publication number: 20220378363
    Abstract: Transient molecules in the gastrointestinal (GI) tract, such as nitric oxide and hydrogen sulfide, are important signals and mediators of inflammatory bowel disease (IBD). Because these molecules may be short-lived in the body, they are difficult to detect. To track these reactive molecules in the GI tract, a miniaturized device has been developed that integrates genetically engineered probiotic biosensors with a custom-designed photodetector and readout chip. Leveraging the molecular specificity of living sensors, bacteria were genetically encoded to respond to IBD-associated molecules by luminescing. Low-power electronic readout circuits (e.g., using nanowatt power) integrated into the device convert the light from just 1 ?L of bacterial culture into a wireless signal. Biosensor monitoring was demonstrated in the GI tract of small and large animal models and integration of all components into a sub-1.4 cm3 ingestible form factor capable of supporting wireless communication.
