A self-healing battery electrode is a battery electrode that repairs mechanical or electrochemical damage autonomously during operation, first demonstrated in 2013 at Stanford and SLAC.
Self-healing ceramic
A self-healing ceramic is a ceramic material or composite that fills its own cracks and recovers strength without external repair, typically through oxidation of embedded agents like silicon carbide.
Self-healing coating
A self-healing coating is a protective coating, usually polymeric, that repairs scratches, cracks, or other defects with minimal or no intervention, restoring corrosion protection to the metal beneath.
Self-healing concrete
Self-healing concrete (SHC) is concrete engineered to repair its own cracks without human intervention, through intrinsic chemistry or added bacteria, microcapsules, or vascular networks that release healing compounds.
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.

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 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 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-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.
Self-instruct
Self-instruct is a method in which a language model generates its own instruction data for finetuning, introduced in December 2022 and used by Stanford's Alpaca.
Self-interference cancellation
Self-interference cancellation is the set of techniques by which a radio receiver removes its own transmitted signal, typically 90 to 120 dB stronger than the desired one, enabling full-duplex operation.
Self-labeling (machine learning)
Self-labeling is a family of semi-supervised machine learning methods in which a model assigns pseudo-labels to unlabeled data and trains on them as ground truth, iterating; FixMatch reached 94.93% accuracy on CIFAR-10 with only 250 labels.
Self-loosening of bolted joints
Self-loosening of bolted joints is the loss of preload, the initial clamping force in a tightened bolt-nut assembly, during service under vibration, impact, or thermal loads, and a main cause of failure in dynamically loaded connections.
Self-Monitoring, Analysis and Reporting Technology
Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) is a system built into hard drives and SSDs that reports internal indicators of drive reliability, adopted by the industry in the 1990s.
Self-motion manifold
A self-motion manifold is the set of all joint configurations placing a robot's end-effector at the same pose, organizing the infinite solutions of redundant manipulator inverse kinematics.
Self-organized task allocation
Self-organized task allocation is a method by which robots or social-insect workers divide tasks through local decisions alone, each responding when a task's stimulus exceeds its internal threshold.
Self-organizing map
A self-organizing map, or Kohonen map, is an unsupervised neural network, introduced by Teuvo Kohonen in 1982, that maps high-dimensional data onto a grid so similar inputs neighbor each other.
