Pressure Tactics


Silicone is the material of choice for breast implants but it can soon be used to make self-healing and bio-compatible materials that mimic human tissues. It is a cushiony material that returns to its original shape after being squeezed. But it has now been found that silicone can become 90 per cent stiffer, just like muscles after a workout, if gently and repeatedly compressed in its liquid crystal phase. This phase is somewhere between a solid and liquid state. When heated, it can return to its normal form.
