Methods and devices for transmitting micromechanical forces locally to induce surface convolutions into tissues on the millimeter to micron scale for promoting wound healing are presented. These convolutions induce a moderate stretching of individual cells, stimulating cellular proliferation and elaboration of natural growth factors without increasing the size of the wound. Micromechanical forces can be applied directly to tissue, through biomolecules or the extracellular matrix. This invention can be used with biosensors, biodegradable materials and drug delivery systems. This invention will also be useful in pre-conditioned tissue-engineering constructs in vitro. Application of this invention will shorten healing times for wounds and reduce the need for invasive surgery.
