The Meridium prosthetic foot was specially designed for moderately active users who navigate varied indoor and outdoor environments and place a high value on intuitive adaptation that replicates natural movement. Constant adaptations within the foot adjust to changes in terrain like uneven ground and slopes. The microprocessor controls the smooth hydraulic rollover and makes walking feel effortless. Automatic heel height adjustment for easy shoe changes. The four-axis kinematics of the Meridium enable especially good adaptation to natural movements while walking. Four axles flexibly connect the toe plate, foot and ankle with one another. The battery and electronics are protected within the ankle area. The integrated microprocessor processes the sensor data and controls the hydraulics in real time. The hydraulics control the plantar flexion and dorsiflexion of the foot independently of one another, thereby uniting flexibility and stability. Movements and forces that occur are recorded by the IMU (inertial motion unit), angle and moment sensors. They provide important information to the microprocessor regarding the user’s situation and gait pattern in order to adapt the Meridium accordingly. This enables the differentiation between standing and walking on level ground as well as on stairs and ramps and the activation of the energy-saving functions, e.g. when sitting. Made from extremely stable yet lightweight titanium, the ankle spring connects the hydraulics in the foot with the pyramid and encloses the electronics and battery in the ankle. The frame and heel spring made from carbon fibre stand out for their high stability and stiffness and also help to protect the hydraulics. The heel spring dampens the step at heel strike. The toe plate made from aluminium with an abducted big toe also forms the link between the carbon frame and the frontal pivot point of the hydraulics. Due to its mobility, very good ground contact is guaranteed during rollover.
