A ski binding release system includes a spring that is releasably maintained in a first state using a pyrotechnic fastener. In the first state, a ski boot is secured in the ski binding. The pyrotechnic fastener is electrically coupled to an activation circuit. The activation circuit includes a battery, a plurality of sensors, a switch, and a controller. When the controller determines that the skier has fallen, the controller generates an output signal that transitions the switch from a disconnected state to a connected state. In the disconnected state, the pyrotechnic fastener is electrically disconnected from the battery. In the connected state, the pyrotechnic fastener is electrically connected to the battery. Electrical energy from the battery causes the pyrotechnical fastener to explode to transition the spring from the first state to a second state to release the ski boot from the ski binding.

Some aspects include a ski binding system using controllable electromagnets, alone or in combination with permanent magnets, as means of attaching or releasing a ski boot to a ski during use. Some aspects include a ski binding system using a controllable solenoid. In some aspects, microprocessor-based control releases binding electronically based on input from sensors located in binding, ski and/or boot, as well as in other equipment or clothing connected to them or to skier, or binding releases when a mechanical threshold is overcome. In some aspects, sensor data are recorded for analysis of system performance and for adjustment and improvement of system parameters based on data analytics.
