生物医学应用中的触觉反馈，例如，人工皮肤修复和微创手术，需要具有高灵敏度和可靠性的多轴检测能力。本文介绍了一种新型的纳米颗粒连续性为基础的多轴传感器的制造，建模和实验特性的范围为0-300 mN的触觉反馈。制造使用喷墨印刷和微成型技术，可扩展到亚毫米尺寸。在垂直方向上的灵敏度为0.037%/mN，在剪切x方向上的灵敏度为0.036%/mN，在剪切y方向上的灵敏度为0.048%/mN。动态特性表明滞后（标准偏差-1.2%）和响应（标准偏差-0.4%）的变化最小，与施加的负载相比，增加应变率。(c)2013爱思唯尔有限公司版权所有。
Tactile feedback in biomedical applications, e.g. prosthetic artificial skin and minimally invasive surgery, requires multi-axial detection capabilities, with high sensitivity and reliability. This paper presents the fabrication, modeling and experimental characterization of a novel nanoparticle resistive-based multiaxial sensor over the range of 0-300 mN for use in tactile feedback. The fabrication uses inkjet printing, and micro-molding techniques scalable to sub millimeter dimensions. Sensitivities of 0.037%/mN in the normal, 0.036%/mN in the shear x and 0.048%/mN shear y directions respectively were achieved. Dynamic characteristics indicated minimal change in hysteresis (standard deviation - 1.2%) and response (standard deviation - 0.4%) compared with the applied load for increasing strain-rates.
