Self-healing conductive polymers
Self-healing conductive polymers are materials that combine electrical conductivity with the ability to repair damage, used in electronic skin, wearable sensors, and flexible energy storage.
Self-healing elastomers
Self-healing elastomers are rubber-like polymer networks that repair cracks caused by mechanical stress, restoring mechanical or electrical function without replacing the material, with uses in tires, seals, and soft robotics.
Self-healing electronic skin
Self-healing electronic skin (self-healing e-skin) is a flexible wearable material that repairs cuts and cracks on its own, restoring mechanical and electrical function; applications include prosthetics, health monitoring, and soft robotics.
Self-healing electronics
Self-healing electronics are electronic materials, circuits, and devices that repair damage without external intervention, restoring conductivity and insulation; approaches include microcapsule healing agents and reversible intrinsic chemistry.
Self-healing flexible energy storage
Self-healing flexible energy storage refers to flexible batteries and supercapacitors built from materials that repair cracks, punctures, and delamination, inspired by biological healing, for wearable and implantable devices.
Self-healing flexible sensors
Self-healing flexible sensors are flexible, stretchable sensors made from materials that repair mechanical damage and restore their sensing function, developed for wearable electronics, electronic skin, and soft robotics.
Self-healing glass
Self-healing glass is a hard, transparent polymer, first reported in 2017 at the University of Tokyo, that re-fuses cracks at room temperature under hand pressure.
Self-healing hydrogels
Self-healing hydrogels are water-swollen polymer networks that repair cuts and cracks on their own, using reversible crosslinks that break and reform; applications include tissue engineering, wound healing, drug delivery, and stretchable electronics.
Self-healing hydrogels via host–guest chemistry
Self-healing hydrogels via host–guest chemistry are water-swollen polymer networks whose reversible macrocyclic host–guest crosslinks let a damaged gel reconnect and recover its strength without external intervention.
Self-healing in halide perovskites
Self-healing in halide perovskites is the spontaneous recovery of photoluminescence, photocurrent, or device performance after damage from light, heat, moisture, or radiation, without external repair. It matters because instability limits commercializing perovskite solar cells.
Self-healing magnetic soft robot
A self-healing magnetic soft robot is a soft robot of magnetically responsive elastomer or hydrogel that repairs cuts and punctures, with magnetic fields driving both actuation and healing.
Self-healing material
A self-healing material repairs its own damage, such as a crack, either autonomously or with external energy or pressure, and spans polymers, concrete, ceramics, and composites.
Self-healing MAX phase ceramics
Self-healing MAX phase ceramics are layered ternary carbides and nitrides that repair their own cracks, chiefly by oxidizing at 700–1300 °C to fill cracks with oxide.
Self-healing metals
Self-healing metals are metals and alloys designed to autonomously repair damage such as microcracks during service, with proposed uses in turbine blades, pipelines, and aerospace parts.
Self-healing of cobalt phosphate oxygen evolution catalysts
Self-healing of cobalt phosphate oxygen evolution catalysts (CoPi) is the continual redeposition of dissolved cobalt ions during oxygen evolution, reported by Kanan and Nocera in 2008.
Self-healing papular mucinosis
Self-healing papular mucinosis (self-healing juvenile cutaneous mucinosis, SHJCM) is a rare localized lichen myxedematosus causing mucinous papules and nodules in children that resolve spontaneously within weeks to months without treatment.
Self-healing perovskite solar cell
A self-healing perovskite solar cell is a perovskite solar cell designed to recover from damage by light, heat, moisture, UV radiation, or mechanical stress, addressing perovskites' instability.
Self-healing piezoelectric composites
Self-healing piezoelectric composites are materials combining piezoelectric function, converting mechanical stress to electric charge, with the ability to repair microcrack damage and restore that function.
Self-healing polymers
Self-healing polymers are polymeric materials that repair damage such as cracks autonomously or under an external stimulus, restoring mechanical strength, thermal conductivity, or electrical function.
Self-healing rubber
Self-healing rubber is rubber or an elastomer that repairs cuts, cracks, and punctures by reforming reversible cross-links, either automatically at room temperature or when triggered by heat, light, or moisture.
Self-healing solid electrolytes
Self-healing solid electrolytes are solid ion-conducting materials, mostly polymers or polymer–ceramic composites, that repair cracks and dendrite damage in solid-state batteries by reforming reversible chemical bonds.
Self-healing solid-state polymer electrolyte
A self-healing solid-state polymer electrolyte is a solid polymer that conducts lithium ions between battery electrodes and repairs cracks and electrode contact damage on its own.
Self-healing supramolecular polymers
Self-healing supramolecular polymers are polymeric materials that repair physical damage through reversible non-covalent bonds, such as hydrogen bonding, which break and reform without added healing agents.
Self-healing transparent conductors
Self-healing transparent conductors are transparent electrode materials, usually dynamic polymers with conductive fillers like silver nanowires, that repair cuts and cracks to restore transmittance and conductivity.
Self-help
Self-help, also called self-development, is the practice of improving one's mental health, behavior, or circumstances without continuous professional treatment, typically through books, structured programs, or digital tools.
Self-help (law)
Self-help (law): unilateral remedy, also called abatement, letting an injured party stop a nuisance, such as cutting encroaching tree branches, without court process; governed by notice rules, the Massachusetts, Virginia, Restatement, and Hawaii rules, and limits on entry and reasonableness.
Self-help group (finance)
A self-help group (SHG) is a member-run savings-and-loan group of 10 to 20 people, mostly women, who save together, lend to each other, and borrow from banks.
Self-image
Self-image is the mental picture a person holds of themselves, closely tied to self-concept, self-esteem, and self-identity; measured chiefly by Rosenberg's 1965 10-item scale, shaped by social comparison, and studied in clinical and body-image research.
Self-immolation of Aaron Bushnell
Aaron Bushnell self-immolation: on February 25, 2024, the 25-year-old active-duty US Air Force senior airman set himself on fire outside the Israeli embassy in Washington, D.C., livestreaming an "extreme act of protest" against the Gaza war, shouting "Free Palestine," and dying of his injuries.
Self-immolative polymer
A self-immolative polymer (SIP) is a stimuli-responsive polymer that depolymerizes completely after one cleavage event, amplifying a single trigger into release of many small molecules; the field began in 2008.
