Abstract
A bio-information measuring apparatus includes: a pulse wave measurer configured to measure a plurality of pulse wave signals from an object; a contact pressure measurer configured to measure contact a pressure between the object and the pulse wave measurer; and a processor configured to obtain a plurality of first envelopes based on the contact pressure and the plurality of pulse wave signals, obtain a second envelope by combining the plurality of first envelopes, and measure bio-information based on the second envelope.
