Textile piezoresistive sensor for detecting a heartbeat and respiratory rate that comprises a lower textile layer, onto which a conductor ink or paste is deposited, such that first conductor strips are defined, while said lower textile layer is attached to a second piezoresistive textile layer, onto which a second conductor strip is placed to which an upper textile layer is finally placed which can receive the ink and/or conductor pastes deposited, said textile piezoresistive sensor being present in a system for detecting a heartbeat and respiratory rate.
