Fig. 3. Acoustic technologies for tissue development.

a Perfusion bioreactors and capillary-based acoustic resonators assemble human articular chondrocytes to form cartilage tissue after long-term culture.

The figures were reprinted and modified from ref. ⁸⁶ by John Wiley and Sons. d Hologram structures are used as acoustic masks to engineer the transmitted acoustic waves and form the designed pressure pattern.
