unavailable in Nature (frequency band gap, waveguiding, topological protection, etc).<br \/>\nIn recent years, PCs and MMs are more and more included as emerging solutions in different fields, from structural health monitoring to sound \/ vibration insulation, to cite a few.<br \/>\nIn this talk, starting from the unconventional assumption that the working principle behind metamaterials is already exploited in Nature, I will present examples of bio-inspired designs of metamaterials with the aim of discussing their potential advantages (and unavoidable limitations) in terms of dynamic \/ static performance with respect to conventional ones.<br \/>\nI will finally discuss potential fields of application (namely, nondestructive evaluation, waveguiding, sound insulation, etc.).<\/p>\n<h4>Summary:<\/h4>\n<p>Phononic crystals (PCs) and elastic metamaterials (MMs) are generally defined as periodic structures with exotic vibrational properties currently unavailable in
