Abstract

The present invention provides a novel ring type sensor for measuring biometric information. The ring sensor includes a rest for an appendage and a wing pivotally connected to the rest. A biasing member supplies a compressive force to the wing (relative to the rest) such that an appendage from which biometric information is to be measured is snuggly held by the rest and the wing.
