“…By virtue of their high sensitivity in response to pressure variations at a particular frequency, cantilever beams (CBs) are utilized as vibration or force sensors in various narrowband applications of pressure or motion detection [ 1 , 2 ]. In addition to well-established applications in atomic force microscopy (AFM) [ 3 , 4 ], scanning force microscopy (SFM) [ 5 ], photothermal spectroscopy (PTS) [ 6 ], and biomolecular sensors [ 7 ], CBs have also been explored for enhanced detection of weak acoustic waves [ 8 ], such as photoacoustic signals [ [9] , [10] , [11] ] in cantilever enhanced photoacoustic spectroscopy (CE-PAS) [ [12] , [13] , [14] , [15] , [16] ] which is a performant spectroscopy method [ 17 ] for trace detection of explosives, pollutants [ 18 , 19 ], illicit drug testing [ 20 ] and industrial monitoring [ 21 , 22 ]. It has been reported that CB enhanced microphones can offer a sensitivity that is 100 times higher than a good quality regular microphone [ 23 ].…”
