Bacterial Signaling

32.3K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

    Area of Science:

    • Biomedical Engineering
    • Wireless Communication Systems
    • Implantable Devices

    Background:

    • Maintaining stable wireless communication with ingestible devices in the dynamic gastrointestinal (GI) tract is challenging due to environmental detuning of antennas.
    • Antenna detuning in the GI tract significantly decreases antenna gain and received signal strength, hindering reliable data transmission.

    Purpose of the Study:

    • To propose and evaluate an air-gap based antenna solution for stabilizing antenna gain and improving wireless communication for ingestible devices within the GI tract.
    • To develop and implement a lightweight security protocol for protecting data transmitted by ingestible devices.

    Main Methods:

    • An air-gap of 1-2 mm was created around a chip antenna to isolate it from the surrounding GI environment.
    • In vitro and in vivo evaluations in swine were conducted to assess antenna gain and received signal strength at 2.4 GHz.
    • A lightweight security protocol utilizing symmetric challenge-response and the Speck cipher was implemented.

    Main Results:

    • The air-gap antenna solution recovered antenna gain and received signal strength by 12 dB or more compared to conventional antennas.
    • Stable wireless communication at 2.4 GHz was achieved, enabling access via mobile devices with Bluetooth Low Energy (BLE).
    • The proposed security protocol provided a secure communication channel with low energy consumption.

    Conclusions:

    • An air-gap antenna design effectively stabilizes antenna performance in the dynamic GI environment, crucial for reliable ingestible device operation.
    • The developed system enables robust and secure wireless data transmission from ingestible sensors using BLE technology.
    • The lightweight security protocol ensures data integrity and confidentiality without significant power overhead.
