The actual paper: https://ieeexplore.ieee.org/document/9178739 https://ieeexplore.ieee.org/document/9178739 The actual novel design for a haptic device: "This paper introduces novel hand-worn hydraulic SSDs (Skin stretch device) that can induce 3-axis tangential forces to the skin via a tactor. The developed SSDs are controlled by new soft microtubule muscles (SMMs) which are driven by hydraulic pressure via custom miniature syringes and DC micromotors." Found it really annoying that the 'scientific writing' piece, in the link, doesn't actually explain what is the novelty and how it works, even after all of that preamble on what it 'could do' in the future.
