通过机械、振动、电触觉和混合系统等侵入性和非侵入性触觉反馈系统，在为截肢者提供感觉方面取得了显着的进步。然而，纯机械驱动的反馈方法却很少被探索。在本文中，我们现在创建了一个触觉反馈系统，不需要任何外部电源（例如电池）或其他电子元件（参见<xref ref-type =“fig”rid =“fig1”>图1</xref>）。该系统成本低、重量轻、适应性强且能够抵御外部影响（例如水）。因此，它在许多方面都是可持续的。我们利用最新的多材料 3D 打印技术 (Stratasys Objet500 Connex3) 能够制造由橡胶 (TangoBlack Plus) 和塑料 (VeroClear) 材料制成的软传感器和机械触觉反馈执行器。当力施加到指尖传感器时，系统内部的流体压力作用在反馈执行器的薄膜上，从而产生机械触觉。我们的 <inline-formula><tex-math notation="LaTeX">$\varnothing 7\,\mathrm{mm}$</tex-math></inline-formula> 反馈执行器能够传输介于 <inline-formula><tex-math notation="LaTeX">$0.2\,\mathrm{N}$</tex-math></inline-formula>（中值触摸阈值）和<inline-formula><tex-math notation="LaTeX">$2.1\,\mathrm{N}$</tex-math></inline-formula>（反馈执行器在 <inline-formula><tex-math notation="LaTeX">$3\,\mathrm{mm}$</tex-math></inline-formula> 压痕处传输的最大力）对应于施加到指尖传感器的力范围<内联公式><tex-math notation="LaTeX">$1.2-18.49\,\mathrm{N}$</tex-math></内联公式>。
Notable advancements have been achieved in providing amputees with sensation through invasive and non-invasive haptic feedback systems such as mechano-, vibro-, electro-tactile and hybrid systems. Purely mechanical-driven feedback approaches, however, have been little explored. In this paper, we now created a haptic feedback system that does not require any external power source (such as batteries) or other electronic components (see <xref ref-type="fig" rid="fig1">Fig. 1</xref> ). The system is low-cost, lightweight, adaptable and robust against external impact (such as water). Hence, it will be sustainable in many aspects. We have made use of latest multi-material 3D printing technology (Stratasys Objet500 Connex3) being able to fabricate a soft sensor and a mechano-tactile feedback actuator made of a rubber (TangoBlack Plus) and plastic (VeroClear) material. When forces are applied to the fingertip sensor, fluidic pressure inside the system acts on the membrane of the feedback actuator resulting in mechano-tactile sensation. Our <inline-formula><tex-math notation="LaTeX">$\varnothing 7\,\mathrm{mm}$</tex-math></inline-formula> feedback actuator is able to transmit a force range between <inline-formula><tex-math notation="LaTeX">$0.2\,\mathrm{N}$</tex-math></inline-formula> (the median touch threshold) and <inline-formula><tex-math notation="LaTeX">$2.1\,\mathrm{N}$</tex-math></inline-formula> (the maximum force transmitted by the feedback actuator at a <inline-formula><tex-math notation="LaTeX">$3\,\mathrm{mm}$</tex-math></inline-formula> indentation) corresponding to force range exerted to the fingertip sensor of <inline-formula><tex-math notation="LaTeX">$1.2-18.49\,\mathrm{N}$</tex-math></inline-formula>.
