MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051644 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 23, for 'cyclic hysteresis-driven molecular rearrangement and self-optimizing foldable display apparatus.'
Inventor(s) include Bapatla Surendra Babu; and Irukumalli Priyanka.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to polymer thermodynamics and flexible optoelectronics. A technical problem is the linear accumulation of cyclic fatigue damage in amorphous polymers driven by constant-energy hysteresis dissipation, leading to premature substrate fracture. The proposed solution is a foldable display apparatus that structurally converts destructive folding energy into constructive material alignment. The apparatus couples a polymeric substrate (110) with a geometric bending constraint to enforce a strict sub-scission deformation regime (140). Under cyclic folding, the strain remains below the chain-scission threshold. Dissipated hysteresis energy forces macromolecular chains (120) to undergo stress-driven free volume redistribution (135) and uniaxial sub-crystalline orientation (125). These morphological changes trigger an elastic shakedown transition (220), wherein initial high-energy hysteresis loops (210) converge toward a non-dissipative stable limit cycle (230). The per-cycle hysteresis energy decays according to a power-law decay hysteresis curve (320), drastically suppressing the decelerating cumulative damage curve (340). The principal use is extending the operational lifespan of foldable electronics without external mechanical reinforcements."
