    Anknüpfend an die Erfolge der letzten Jahre wurden auch 2018 die Beiträge der Fritz-Hüttinger-Professur für Mikroelektronik bei der IEEE International Solid-State Circuits Conference (IEEE ISSCC) 2018 akzeptiert. Der Beitrag

     A Fully Immersible Deep-Brain Neural Probe with Modular Architecture and a Delta-Sigma ADC Integrated Under each Electrode for Parallel Readout of 144 Recording Sites

    von D. De Dorigo, C. Moranz, H. Graf, M. Marx, B. Shui, M. Kuhl und Y. Manoli wurde als das Highlight der Sitzung "Advanced Biomedical Systems" gekürt.

    Zitat (IEEE ISSCC Press Kit):

    "Context and State of the Art

    • Tissue-penetrating probes for high-density deep-brain recording of in vivo neural activity provide important tools for neuroscience exploration and disease management.
    • Conventional devices need either a large number of interconnects at the base of the probe or allow only a reduced number of electrodes to be read out simultaneously.

    Technical Highlights

    • First reported reconfigurable miniaturized probe, with a single 11.5mm-long 70μm-wide needle shank without a base.
    • Parallel readout of all 144 integrated recording sites.
    • Incremental delta-sigma analog-to-digital converters (ΔΣ-ADC) integrated within 70x70μm2 area under each electrode avoid global routing of noise-sensitive neural signals.
    • Smallest external 8-wire interface, including supplies, biases, and digital.

    Applications and Economic Impact

    • Slim shaft of 70μm from top to bottom can potentially improve neural recording quality and longevity for chronic brain monitoring.
    • Chronic recording of neural signals from the brain accelerates understanding of neurological diseases and improves health outcomes."
