Smart shoe module

A smart shoe module comprising:

• an upper case provided to define an upper exterior of a pressure switch and configured to be elastically movable by a specific pressure value or more activating in a first direction;
• a lower case coupled to a lower end of the upper case and provided to define a lower end exterior of the pressure switch;
• a circuit board loaded in the lower case and comprising a first circuit unit;
• a piezo element provided between the upper case and the first circuit unit of the circuit board and configured to generate a signal in the first circuit unit according to the elastic motion;
• and
• a controller implemented to process the signal generated in the first circuit unit,
• wherein the controller calculates a user's momentum based on a voltage of a signal generated in the first circuit unit.

A smart shoe module system comprising:

• a left smart shoe module and a right smart module,
• wherein each of the left and right smart shoe modules comprises,
• an upper case provided to define an upper exterior of a pressure switch and configured to be elastically movable by a specific pressure value or more activating in a first direction;
• a lower case coupled to a lower end of the upper case and provided to define a lower end exterior of the pressure switch;
• a circuit board loaded in the lower case and comprising a first circuit unit;
• a conductive member configured to form a first gap in the upper case, together with the first circuit unit, and generate a signal in the first circuit unit according to the elastic motion;
• a motion sensor comprising an acceleration sensor and a gyro sensor;
• and
• a controller implemented to process the signal generated in the first circuit unit,
• wherein the controller is configured to calibrate a rate of on-signals measured by the first circuit unit provided in each of the left and right smart shoe modules to a calibrated on-signal rate, based on a rate of a ground supporting time analyzed by each of the motion sensors.
