“…The micro-air pulse delivers a localized impulse stimulus towards the surface of tissues in order to produce a wave perturbation. It was firstly proposed in [93,94], and since then, it has been applied to the generation of SAWs for the elastography of diverse tissues, including cornea [20,26,62,[95][96][97][98][99][100][101], skin [13,102,103], cardiac and skeletal muscles [104][105][106], and cartilages [107], to name just a few applications. Air-pulse stimulation has advantageous properties relevant for its clinical translation, including its non-contact coupling with tissues, the generation of small loading pressures (in the mPa range), and the precedent of being used safely in other screening devices in ophthalmology [108,109].…”
