  Helicobacter pylori, a pervasive bacterial infection associated with
gastrointestinal disorders such as gastritis, peptic ulcer disease, and gastric
cancer, impacts approximately 50% of the global population. The efficacy of
standard clinical eradication therapies is diminishing due to the rise of
antibiotic-resistant strains, necessitating alternative treatment strategies.
Photodynamic therapy (PDT) emerges as a promising prospect in this context.
This study presents the development and implementation of a magnetically-guided
origami robot, incorporating flexible printed circuit units for sustained and
stable phototherapy of Helicobacter pylori. Each integrated unit is equipped
with wireless charging capabilities, producing an optimal power output that can
concurrently illuminate up to 15 LEDs at their maximum intensity. Crucially,
these units can be remotely manipulated via a magnetic field, facilitating both
translational and rotational movements. We propose an open-loop manual control
sequence that allows the formation of a stable, compliant triangular structure
through the interaction of internal magnets. This adaptable configuration is
uniquely designed to withstand the dynamic squeezing environment prevalent in
real-world gastric applications. The research herein represents a significant
stride in leveraging technology for innovative medical solutions, particularly
in the management of antibiotic-resistant Helicobacter pylori infections.
