Background:

Implantable memristors offer brain-like memory simulation for biomedical use.
Enhancing long-term stability and biocompatibility is crucial for implantable devices.

Purpose of the Study:

To fabricate and validate a stable, biocompatible implantable memristor.
To assess the device's performance in simulated biological environments.

Main Methods:

Fabrication of a TiO2-based memristor using magnetron sputtering.
Testing thermal stability at elevated temperatures.
Long-term performance evaluation in biological mimicking environments (fresh pork, bullfrog tissues).

Main Results:

The memristor exhibited excellent thermal stability and recoverability.
Consistent bipolar resistive switching (RS) characteristics and stable memory performance were maintained in biological tests.
Device operation was primarily governed by space charge limited currents, Ohmic conduction, and Schottky emission.

Conclusions:

The implantable memristor demonstrates validated long-term stability in real biological environments.
This work promotes the practical application of implantable memristors in medicine.
The findings lay the groundwork for future biomedical integration of memristor technology.
