Manufacturing scalability represents a significant barrier to commercial viability. Current fabrication methods for transient electronics typically involve complex, multi-step processes that are difficult to integrate with established textile manufacturing workflows. The precision required for depositing degradable electronic components onto fabric substrates demands specialized equipment and expertise not readily available in traditional textile production facilities.

Environmental variability poses substantial challenges for controlled degradation mechanisms. Smart fabrics encounter unpredictable exposure to moisture, temperature fluctuations, mechanical stress, and chemical agents during normal use. Designing transient electronics with predictable dissolution timelines under such variable conditions remains technically challenging, risking either premature degradation or persistent environmental presence beyond intended lifespans.

Biocompatibility concerns emerge particularly for smart fabrics designed for direct skin contact or medical applications. The degradation byproducts of transient electronics must be non-toxic and non-irritating, yet current materials often produce intermediate compounds requiring further investigation for long-term safety. This challenge becomes more pronounced for wearable health monitoring applications where prolonged skin contact occurs.

Signal integrity and electromagnetic interference issues also plague current transient electronic systems in textiles. The degradable nature of conductive pathways can lead to increasing impedance over time, resulting in signal deterioration. Additionally, the proximity of multiple transient components in a confined fabric area creates potential for cross-talk and interference, compromising overall system reliability.

Transient electronics in smart fabrics is evolving rapidly, currently transitioning from early development to commercialization phase.
