Researchers demonstrated a self-healing crystalline material, which can automatically repair broken phone screens in seconds. The researchers at the Indian Institute of Science Education and Research (IISER) in Kolkata and the Indian Institute of Technology Kharagpur said they were inspired by wound and bone healing.
- The researchers developed a solid material in the crystalline state.
- When the material is broken in the crystalline state, opposite electric potentials are activated at the fractured ends.
- The characteristic enabling this is called "piezoelectric," which means the material can convert mechanical energy into electricity and vice-versa.
- Piezoelectricity is also a significant factor enabling natural biomaterials to self-heal, including for damaged bones and collagen.
- Last week, the researchers published a study about this new material in the journal Science.
