Crystal adaptronics - study of dynamic crystals that exhibit macroscopic motion in response to heat, light, and other stimuli - has grown to be a vibrant research field in the past two decades, even though the first examples of such systems were documented since the 1980s. The reason can be sought in the prospects for numerous applications of such materials as microscopic crystalline switches that range from wearable electronics to biomedical sciences and practice. The mechanical responses include motility such as displacement, jumping, and even explosion, and reshaping such as bending, curling, twisting, or coiling. It has been demonstrated recently that some of these effects occur in a predictable manner that can be described mathematically. In this chapter we present a simplified summary of mathematical interpretation of crystal bending, the simplest of these well-explored effects. We also highlight new directions in this research field, such as studies of salient and self-healing crystals, which are documented but much less understood than the bending crystals.
