TL;DR: A model fish with a man-made swim bladder achieves fast vertical motions based on density adjustments in a pressure-responsive way when exposed to a magnetic field, working with pressure differences in the blood-pressure range and at the frequency of a beating heart.

TL;DR: This study develops a light-responsive functionally cooperating smart device that can directly harvest naturally available light energy for diving-surfacing motions, thus converting mechanical energy into electricity through Faraday's law, and may promote the concept of a functionally cooperating system as an economic and facile power supply for microelectronics, reducing their dependence on batteries.

TL;DR: In this paper, a pH responsive smart surface is combined with the reaction between CaCO3 and HCl to develop a new minigenerator, which can convert mechanical energy generated from the chemical reaction into electrical energy through cutting magnetic lines with moving conductive lines.

TL;DR: In this article, a mini-generator was designed and fabricated to perform a diving-surfacing cycled motion with an intelligent initiation based on pH-responsive materials, and the obtained mechanical energy can be converted into electricity through cutting the strong magnetic line with a conductive line.

TL;DR: This research field with emphasis on the demonstration of self-propulsion is introduced, the underlying principles for integrating multiple smart materials with typical examples are summarized, and an insight into functionally cooperating systems is believed to motivate innovative strategies for the systematic integration of smart materials.
