expanders
Things that widen
Expanders are devices or substances that increase the size or capacity of something.
Tissue expanders stretch skin before reconstructive surgery.
Palate expanders widen the upper jaw in orthodontics.
In audio, expanders increase the dynamic range of a signal—the opposite of compressors.
The word applies broadly to anything designed to enlarge, extend, or create more space: foam expanders for tight shoes.
