We have measured resistivity as a function of temperature and pressure of Ti<Subscript>4</Subscript>O<Subscript>7</Subscript> twinned crystals using different contact configurations. Pressures over 4 kbar depress the localization of bipolarons and allow the study of the electrical conduction of the bipolaronic phase down to low...</subscript></subscript>
