Safety shoes’ olfactory sensor ‘: can detect toxic gases and sound an alarm

The intelligent gas detection safety shoes launched by Safetech Solutions in South Korea are redefining industrial safety protection standards. This innovative product integrates a high-sensitivity gas sensor array inside the insole, which can monitor the concentration changes of five common hazardous gases such as hydrogen sulfide and methane in real time.

When the gas concentration exceeds the standard, the system will issue dual alarms through heel vibration and mobile app to ensure that workers receive timely warnings. In actual testing, the response speed of the system is 8-12 seconds faster than traditional handheld detectors, providing a more reliable safety guarantee for operations in hazardous environments.

The company plans to launch two versions in the fourth quarter of 2025: the base version priced at $180, suitable for regular work environments; The high-end customized version adds cloud data analysis and team management functions, with a starting price of $300. At present, multiple international petrochemical groups have expressed their purchasing intentions, and it is expected that the first batch of orders will exceed 50000 pairs.
