Biological tissues are mainly constituted of soft matter. This very particular state, neither liquid, nor gaseous, nor solid, leads for simulation to the use of mathematical models more and more complex. Moreover, these tissues are arranged in multi-layer way, they are anisotropic and they have not mechanical linear properties. The evaluation of the interface pressures by traditional methods leads to measurement errors. FORSAFE is a sensor of the pressure between newborn's head and forceps allowing to limit hazards due to bad positioning and too important tightening of the forceps during the delivery. It is based on an original bio-inspired method reproducing the touch sense by micropalpations.
