Technology that allows smartphones to detect and visualize heat signatures, creating images based on temperature differences rather than visible light, is now available. A practical example is identifying insulation leaks in buildings by pinpointing areas of significant heat loss using a mobile device.
The integration of this capability into mobile devices offers a significant advantage for various applications, ranging from building inspection and maintenance to search and rescue operations. Historically, such technology was expensive and confined to specialized equipment; its miniaturization and accessibility on everyday devices represent a notable advancement.
