For diabetes patients, a small wound on the foot is like a time bomb. When the sensation in the feet becomes dull due to peripheral neuropathy, one may not feel pain even if a small stone in the shoe pierces the skin. This wound can develop into an ulcer and eventually lead to the terrible chain reaction of amputation—a sequence that 'Internet of Things (IoT) sensors' can perfectly disrupt.
Up to 30 days before an ulcer (wound) becomes visible to the naked eye, 'subtle temperature rises' occur within the skin of the affected area due to inflammation. Modern smart insoles or smart socks have dozens of high-precision temperature and pressure sensors embedded in them to scan these minute heat changes (Hot Spots) in real-time.
"The temperature of a specific area on your right foot is more than 2.5 degrees high. There is a risk of ulceration; please stop walking immediately and check your foot."
Early smart socks were difficult to wash, making them inconvenient for seniors to use daily. To compensate for this, smart insoles have emerged. Parents can simply slip these insoles into the sneakers or walking shoes they normally enjoy wearing. Pressure concentration and temperature data applied to the soles of the feet while walking are automatically transmitted to a smartphone app.
💡 Data Sharing with Guardians: If a parent's foot pressure data abnormally shifts to one side (asymmetric walking to avoid pain), a push notification is immediately sent to the child's smartphone. Seeing this notification, the child can hurry to make a hospital appointment.
