Abstract | Mammalian mechanoreceptors endow the skin with the ability to perceive mechanical stimuli with precision. However, the fabrication of artificial mechanoreceptors with high sensitivity and resolution over a wide linear pressure range remains a key challenge. Herein, an artificial ion mechanoreceptor with the core-shell structured nanofibrous membrane as the sensitive layer is proposed by mimicking the biomechanical receptor. The membrane embeds ionic liquids and poly(vinylidene fluoride-co-hexafluoropropylene) hybrid nanofibers into a thermoplastic polyurethane matrix, enabling a reversible conversion between non-ionic and iontronic sensing modes induced by tactilely triggered ion movements. It exhibits a high sensitivity (32.70 kPa), a linear response (R ≈ 0.999) over a wide range of 0.04 Pa to 209 kPa, and an ultra-high resolution of 0.035% at 100 kPa (far exceeding the resolution of skin of ∼7%). The receptors are further used to monitoring physiological signals (even weak fingertip pulse signals) and assembled into an array to aid object recognition. |
