MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202611022892 A) filed by Panipat Institute Of Engineering And Technology, Samalkha, Haryana, on Feb. 26, for 'bio based microcapsule enabled autonomous self healing concrete system and method thereof.'
Inventor(s) include Er. Deepak Juneja.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a bio-based microcapsule-enabled autonomous self-healing concrete system for enhancing durability and service life of concrete structures. The system comprises a cementitious matrix incorporating a plurality of uniformly dispersed biodegradable microcapsules encapsulating one or more bio-derived healing agents. Upon formation of micro-cracks within the concrete due to mechanical, thermal, or environmental stresses, the microcapsules rupture as a result of localized stress concentrations and release the healing agents into the crack region. In the presence of moisture and atmospheric components, the released agents initiate bio-mineralization, enzymatic, or polymerization reactions that produce mineral or bio-polymeric sealing compounds, thereby filling and sealing the micro-cracks, reducing permeability, and restricting ingress of aggressive substances. The autonomous self-healing mechanism operates without external intervention, is compatible with conventional concrete materials and construction practices, and provides an environmentally sustainable solution for reducing maintenance requirements and lifecycle costs in infrastructure applications."
