Phononic waveguides (PnWGs) are devices with rationally designed periodic structures to manipulate mechanical oscillations and engineer control the propagation of acoustic waves, thus allowing for frequency band selection wave transmission routing, promising both classical quantum transduction on chip-scale platforms various constituent materials interest. They can be incorporated into electromechanical optomechanical signal schemes. Here, we present an overview emerging micro/nanoscale PnWGs offer perspectives future. We evaluate typical structural designs, scaling, phononic PnWGs. Material choices, fabrication techniques, characterization schemes discussed based different PnWG designs. For schemes, all-phononic integrated circuit perspective is proposed. Toward applications, potential utilizing as universal interfaces channels has been examined. envision extraordinary properties, such nonreciprocity active tunability, realized unconventional design strategies (e.g., inverse design) advanced van der Waals layered crystals), opening opportunities in
