The invention discloses a self-generating multifunctional intelligent insole. The insole mainly comprises three 
layers, wherein the upper layer adopts a multilayer film process and has the effects of ventilation, 
antibiosis and magnetotherapy, the middle layer adopts a wearable material with light texture and compression resistance, the middle layer is embedded with flexible pressure sensors, a motion sensor, miniature 
infrared emitting 
diode and 
photodiode, a flexible pressure power generating device and a 
data acquisition circuit 
system, and the bottom layer adopts an antibacterial material with higher 
hardness. The flexible pressure sensors are mainly arranged at the first phalange, the 
first metatarsal bone, the second metatarsal bone, the third metatarsal bone, the fourth metatarsal bone, the 
fifth metatarsal bone, the lateral of the arch and the middle of the 
heel. The miniature 
infrared emitting 
diode and 
photodiode are arranged below the transverse 
artery of the first 
toe. The 
data acquisition circuit 
system comprises a 
signal conditioning module, a main control 
chip, a data storage module, a 
power management module and a 
wireless transmission module. The insole can measure the pressure distribution on the 
sol, the 
heart rate, the motion state and other parameters, and can be connected with intelligent terminals such as a 
mobile phone, a computer and the like through 
wireless communication, thereby carrying out 
data processing analysis and real-time display, and further providing the functions of detecting 
recovery, counting steps in motion, correcting the walking posture and the like.
