Principle of intelligent constant temperature energy storage insole

Why should you invest in an intelligent insole system?

An intelligent insole system may monitor the individual’s foot pressure and temperature in real-time from the comfort of their home, which can help capture foot problems in their earliest stages. Constant monitoring for foot complications is essential to avoid potentially devastating outcomes from common diseases such as diabetes mellitus.

How does a smart insole system work?

The smart insole system mainly comprises a 24-channel CPS array, a DAQ circuit with a wireless transmitter, and a PC terminal with a wireless receiver, with the circuit diagram depicted in Fig. 3a. First, for the 24-channel CPS array (red dashed box), the sensors are distributed in the insole according to the configuration in Fig. 3b.

How far can a smart insole work?

If the smart insole can work within a range of 15-20 meters, that is more than enough since the gait cycle analysis of a patient can smoothly be done within this range. But nevertheless, performing the experiment outdoor will provide around 4x range. The data were collected from 12 subjects.

Can a smart insole be a sustainable power source for wearable bioelectronics?

A total of 260 light-emitting diodes were lit up with perspiring feet and water on the floor, and a capacitor of 88 μF was charged to 2.5 V in 900 s. This work represents a practical approach to developing a highly efficient and robust smart insole that can be used as a sustainable power source for wearable bioelectronics.

How many FSR & temperature sensors are in an insole?

Multiplexing and Data Logging Unit Each insole contains 16 FSRs and 8 temperature sensors. Readings from them must be multiplexed and represented in a single string before wirelessly transferring data from the peripheral to the central device (connected to a PC and insole).

Can a wearable insole detect plantar pressure and temperature?

Constant monitoring for foot complications is essential to avoid potentially devastating outcomes from common diseases such as diabetes mellitus. Inspired by those goals, the authors of this work propose a full design for a wearable insole that can detect both plantar pressure and temperature using off-the-shelf sensors.
