Climfeet (on the market): The thermal protection time of shoes required by the standard is 30 minutes, while construction workers, cold storage workers or military personnel are exposed 8 hours/day, athletes run for about 2 hours and patients with Raynaud's disease always have cold feet. Climfeet with many air cushions warms the feet in winter and cools them in summer, like a heat pump, without batteries or time limits. Warnfeet (in development): Clinical trials have shown that monitoring foot pressure and temperature can predict the onset of ulcers. Warnfeet with 150 self-powered piezoelectric pressure and temperature sensors in a thin (3 mm) and flexible silicone insole connected without batteries: with each step, the sensors provide the energy needed to send alerts to the smartphone. Warnfeet could also monitor and analyze the risk of blister, the gait and well-being.
