Morphology

ultrasensitive = sensitive (transparent) = ultra + sense + itive

The meaning is a direct intensification of 'sensitive' by the prefix 'ultra-'.

Etymology

Ultrasensitive comes from ultra- 'beyond' (as in ultraviolet) and sensitive 'able to notice small things'. So, it describes a device, test, or skin that can detect even the smallest signals or changes.
