This abstract first appeared for US patent application 20250121793 titled 'SYSTEM OF ON-DEMAND TUNABLE STIFFNESS FOR PEDESTRIAN PROTECTION
Original Abstract Submitted
a vehicle includes a first vehicle component having a shape memory polymer (smp) including a first modulus of elasticity in a first state and a second modulus of elasticity in a second state, the second modulus of elasticity being less than the first modulus of elasticity, a heating element selectively movable from an off state to an on state to supply the smp with heat, the smp moving from the first state to the second state in response to the heating element moving from the off state to the on state, and at least one sensor attached to the vehicle and configured to generate an electric signal in response to a force of a predetermined magnitude being applied to the vehicle to move the heating element from the off state to the on state.
