| description | The invention discloses a micro valve and a method for controlling the transport of a fluid by virtue of the micro valve. The micro valve comprises a piezoelectric substrate, wherein an interdigital transducer is arranged on the working surface of the piezoelectric substrate, and a first PDMS (polydimethylsiloxane) microgroove is formed in a sound transmission path of sound acoustic waves excited by the interdigital transducer; an opening in the top end of the first PDMS microgroove is covered by heat conduction sheet metal; a second PDMS microgroove is formed in the upper surface of the heat conduction sheet metal; a soft PDMS slice is connected to the opening in the top end of the second PDMS microgroove; a PDMS polymer is connected to the top end of the second PDMS microgroove; two micro-channels are soft-photoetched in the PDMS polymer; nicks communicated with the micro-channels are formed in positions, corresponding to the soft PDMS slices, at the bottom end of the PDMS polymer; the edges of the nicks ar |
