Scientists have re-discovered the 'shiner':

Electronic-skin technologies for prosthetics and robots can detect the slightest touch or breeze. But oddly, the sensors that make this possible do not respond effectively to a harmful blow. Now researchers report in ACS Applied Materials & Interfaces the development of a jellyfish-inspired electronic skin that glows when the pressure against it is high enough to potentially cause an injury.

An electronic skin that can mimic the full range of biological skin's sensitivity has great potential to transform prosthetics and robotics. Current technologies are very sensitive, but only within a narrow range of weak pressures.

Under high pressures that could cause damage, the electronic skins' sensitivity fades. To address this shortcoming, Bin Hu and colleagues at the Huazhong University of Science and Technology turned to the Atolla jellyfish for inspiration.

This bioluminescent, deep-sea creature can feel changes in environmental pressure and flashes dramatically when it senses danger.
