Background:

Resorbable, implantable bioelectronic devices offer real-time physiological monitoring.
Degradable magnesium-based electronics are pioneers, but short functional lifetimes hinder clinical translation.
Flexible, resorbable barrier films are needed to tune device longevity.

Purpose of the Study:

To develop tunable barrier films for resorbable bioelectronic devices.
To create a library of stereocontrolled succinate-based copolyesters.
To enhance the functional lifetime of transient bioelectronic prototypes.

Main Methods:

Synthesized a library of stereocontrolled succinate-based copolyesters.
Investigated the impact of copolymer composition and processing on material properties.
Evaluated the barrier properties and resorption timelines of the developed copolyesters.

Main Results:

Developed copolyesters with tunable thermomechanical, crystalline, and barrier properties.
One copolymer composition significantly extended the functional lifetime of bioelectronic prototypes by several weeks.
Demonstrated a viable method for controlling device lifetime through barrier film engineering.

Conclusions:

Succinate-based copolyesters offer tunable barrier properties for resorbable electronic devices.
Engineered barrier films can significantly extend the operational lifespan of transient bioelectronics.
This advancement represents a considerable step towards the clinical translation of resorbable bioelectronic devices.
