Background:

Memristors, the fourth fundamental passive circuit element, are crucial for novel computing architectures that merge storage and processing.
Physarum polycephalum, a unicellular slime mold, exhibits adaptive behaviors and produces pinched hysteresis loops under AC voltage, mimicking memristor characteristics.

Purpose of the Study:

To engineer bio-memristors and bio-computing devices using Physarum polycephalum.
To develop a standardized method for culturing P. polycephalum as an electronic component.

Main Methods:

Developing a specialized receptacle for culturing P. polycephalum.
Applying AC voltage to P. polycephalum to observe its current-voltage characteristics.
Implementing P. polycephalum as a bio-memristor in electronic circuits.

Main Results:

Physarum polycephalum demonstrates pinched hysteresis loops, confirming its memristive properties.
The developed method significantly reduces organism growth time.
The lifespan of the bio-memristor components is increased, and electrical observations are standardized.

Conclusions:

Physarum polycephalum can be effectively utilized as a biological memristor.
The novel bio-memristor implementation offers a promising foundation for future bioelectronic systems and computing.
This research advances the integration of biological organisms into electronic circuit design.
