# Muscle-Cell-Based "Living Diodes"

## TL;DR

This paper introduces a novel bioelectronic diode constructed from living muscle and fibroblast cells, capable of unidirectional signal transmission, representing a significant advancement in biohybrid device design.

## Contribution

It presents the design, fabrication, and characterization of the first living diode using muscle and fibroblast cells for unidirectional electrical signaling.

## Key findings

- The living diode allows signal passage in one direction only.
- The device demonstrates functional unidirectional electrical conduction.
- This approach opens new avenues for biohybrid electronic components.

## Abstract

A new type of diode that is made entirely of electrically excitable muscle cells and nonexcitable fibroblast cells is designed, fabricated, and characterized. These two cell types in a rectangular pattern allow the signal initiated on the excitable side to pass to the nonexcitable side, and not in the opposite direction.
