technosignature
/ˌtɛknoʊˈsɪɡnətʃər/
Definition
Any measurable property or effect that provides scientific evidence of past or present extraterrestrial technology.
Etymology
The word is a hybrid construction combining the Greek 'technē' (art, craft, or skill) with the Latin 'signatura' (a sign or mark). It emerged in the 21st century within the SETI community to distinguish artificial signals from naturally occurring biological signatures.
