Superior Ideas is a crowdfunding website, where anyone can contribute any amount to help support research projects. Donations are tax-deductible, too. One great example:
Soft Robotic Component with a Mussel Tone
Development of these soft machineries help advance medical devices that interface with biological systems (e.g., microsurgery), prostheses with improved implant-tissue compatibility (e.g., neuroprosthesis), and biomaterials for regenerating diseased tissues.
