Passive five sensor insole real-time feedback device

A feedback device for a person comprising:

• an insole adjacent to a foot in a shoe worn by said person, said foot exerting a force on said insole while said person is walking, said foot having a heel, a fifth metatarsal head, a first metatarsal head, a space between a second metatarsal head and a third metatarsal head, and a big toe;
• five force sensors in said insole for measuring the force of said foot of said person while taking steps with each sensor generating a force data signal;
• said five sensors are positioned under said heel, said fifth metatarsal head, said first metatarsal head, said space between said second metatarsal head and said third metatarsal head, and said big toe of said foot,
• a microprocessor for receiving each force data signal from each sensor and processing said force data signals and comparing said processed data signal against a baseline,
• a haptic device for generating vibrations to said person upon receipt of a signal from said microprocessor;
• said microprocessor sending such signal if said process data signal meets or exceeds the baseline, to indicate to said person that said person has placed enough weight upon his/her foot to safely take the next step,
• a wireless communications device;
• a smart phone, said microprocessor sending such signal if said process data signal meets or exceeds the baseline through said wireless communications device to said smart phone;
• an application running on said smart phone, said application upon receipt of a signal from said microprocessor, generating a visual, audio, or vibration feedback display in said smart phone to indicate to said person that said person has placed enough weight upon his/her foot to safely take the next step;
• and
• a force concentrator adjacent to each force sensor of said five force sensors, said force concentrator having a larger surface area than said adjacent force sensor for increasing the effective area of each sensor for measuring the force of said person with each sensor generating a force data signal.
