Foot ulcers often developed due to repetitive trauma on the feet of patients who have lost their protective sensation, including people affected by diabetic neuropathy. Broadly, foot ulcers, infections, and gangrene are diabetes-related foot disorders (DFD) and are the key cause of the global disability burden. High plantar pressures, an abnormal gait, hyperglycemia, hypertension, and dyslipidemia are significant risk factors for DFD recurrence and complications in those at risk for DFD. With the use of telehealth management and a variety of sensors and wearables that have been developed or are presently being developed, it is now feasible to provide remote care for individuals who are at risk for DFD.

According to the National Diabetes Statistics Report, published by the Centers for Disease Control and Prevention in June 2022, around 37.3 million people are suffering from diabetes among which the U.S. alone has a share of 11.3%. Overall, about 5% of patients with diabetes mellitus develop foot ulcers and 1% end up with an amputation. Around 3.3 million people in the UK are suffering from diabetes and this is anticipated to increase to 5 million by the end of 2025. The NHS spends almost USD 1.38 billion every year on diabetic foot ulcer-related care. There are over 60,000 people with diabetic foot ulcers in England, and 160-foot ulcer-related amputations every week, over 60% of these people die within five years of amputation.

Additionally, peripheral neuropathy is thought to affect between 6% and 51% of persons with diabetes, depending on factors like age, length of diabetes, glucose control, and type 1 versus type 2 diabetes, according to a study published by NCBI. Around, 60% of diabetic foot ulcer comes from neuropathy. Thus, early detection of foot ulcers would benefit particularly diabetes individuals to reduce the risk of amputation. The primary recommendations for preventing diabetic foot ulcers are daily foot inspections, temperature monitoring, and orthotic shoes.

The foot ulcer sensors are inclusive of optical sensors, thermal sensors, red-green-blue (RGB) sensors, flexiforce sensors, and biosensors. These sensors are mainly used for the self-management and monitoring of the foot to identify the initial appearance of the foot ulcers, monitor the existing ulcers, and possible recurrent ulcerations. The sensors are used to identify the symptoms related to the DFD. The signs/symptoms involve temperature change, color change (excessive redness), skin damage due to irregular foot plantar pressure, swelling or odor, or a change in pain level. Various optical and laser sensors are used to capture this indication to prevent the foot ulcer from worsening. Recently, thermal sensors or RGB sensors have had lesser acquisition costs and can be integrated with portable devices. Additionally, sensors are used to identify and monitor factors including foot deformities/wounds, glucose levels, hemoglobin concentrations, and temperature. All these factors can be currently monitored with the usage of various sensors.

A number of commercially available systems, including Pedar and F-Scan systems, are available for monitoring plantar pressure in the foot. The only people who can afford these systems, though, are professional athletes. The force exerted against the bottom of the foot is measured by small inserts called in-shoe sensors. To stop DFUs, smart insoles and socks have been developed. Through behavior modification or the early diagnosis of injuries, diabetics can take a more active role in the care of their feet with the help of these devices. The SurroSense Rx shoe insert by Orpyx includes a textile pressure sensor. Wearers can alter their gait to prevent injury to their feet through real-time monitoring of pressure levels. For people with peripheral neuropathy who have decreased sensation, this is enormously beneficial. The integrated sensors in Siren's smart socks track daily temperature variations to look for early indications of harm. This is due to the fact that an increase in skin temperature is associated with inflammation, one of the initial indicators of injury. The smart insoles from Bonbouton also keep track of temperature changes. Their device measures the temperature differences between the wearer's feet and alerts the user when there is a significant difference, which indicates that the foot with the higher temperature has less blood flow. This is concerning because ischemia is another reason why DFUs occur.
