									<p style="text-align: left; color: #1b96cf; font-size: 24px;">测试软性、柔性材料的重要性<strong><u><i><br></i></u></strong></p>
<p>非常柔软和灵活的样品的一个例子是微电子机械系统。MEMS被用于日常商业产品，如打印机、移动电话和汽车[1]。它们的用途还包括特殊功能，如生物传感器[2]和能量采集[3]。对于它们的应用，MEMS必须能够在其原始配置和压缩配置之间反复可逆地过渡[4]。为了了解这些结构对机械力的反应，可以进行压缩测试。压缩测试可以用来测试和调整各种MEMS配置，以及测试这些样品的上限和下限力。</p>
<div>&nbsp;纳诺维亚酒店 <a href="https://nanovea.com/mechanical-testers/">机械测试仪</a> <a href="https://nanovea.com/nano-indentation-tester/">纳米 </a>模块能够在极低负载下准确收集数据并移动超过 1 毫米的距离，使其成为测试柔软样品的理想选择。通过具有独立的载荷和深度传感器，大的压头位移不会影响载荷传感器的读数。与其他纳米压痕系统相比，我们的系统能够在超过 1 毫米的压头行程范围内进行低负载测试，这使得我们的系统独一无二。相比之下，纳米级压痕系统的合理行进距离通常低于 250μm。 </div>
<div>&nbsp;</div>
<p style="text-align: left; color: #1b96cf; font-size: 24px;">测量目标</p>
<p>在这个案例研究中，Nanovea对两个独特的不同的柔性弹簧状样品进行了压缩测试。我们展示了我们在非常低的负载下进行压缩和记录大位移的能力，同时准确地获得低负载下的数据，以及如何将其应用于MEMS行业。由于隐私政策，本研究中不会透露样品和它们的来源。</p>

<p style="text-align: left; color: #1b96cf; font-size: 24px;">测量参数<strong><u><i><br></i></u></strong></p>
<p><a href="https://nanovea.com/wp-content/uploads/2019/04/Table-1.png"><img decoding="async" src="https://nanovea.com/wp-content/uploads/2019/04/Table-1.png" alt="" width="748" height="202"></a></p>
<p>注：当压头在空气中时，1V/min的加载速率与大约100μm的位移成正比。</p>
<p style="text-align: left; color: #1b96cf; font-size: 24px;">结果和讨论<u><i></i></u></p>
<p style="margin: 0in; margin-bottom: .0001pt;"><span style="font-family: 'Arial',sans-serif;">样品对机械力的反应可以从载荷与深度的曲线中看出。在上述的测试参数下，样品A只显示出线性弹性变形。图2是一个很好的例子，说明在75μN的载荷与深度曲线上可以实现的稳定性。由于载荷和深度传感器的稳定性，很容易察觉到样品的任何明显的机械反应。 </span></p>
<p style="margin: 0in; margin-bottom: .0001pt;"><span style="font-family: 'Arial',sans-serif;">样品B显示出与样品A不同的机械反应。超过750μm的深度，图表中开始出现类似断裂的行为。这可以从深度为850和975μm时载荷的急剧下降中看出。尽管在8mN的范围内以高负荷率行驶超过1mm，我们高度敏感的负荷和深度传感器允许用户获得以下光滑的负荷与深度曲线。 </span></p>
<p style="margin: 0in; margin-bottom: .0001pt;"><span style="font-family: 'Arial',sans-serif;">硬度是由负载与深度曲线的卸载部分计算出来的。刚度反映了使样品变形所需的力有多大。对于这个刚度的计算，使用了0.3的伪泊松比，因为材料的实际比率是不知道的。在这种情况下，样品B被证明比样品A更硬。</span></p>

<p>使用Nanovea机械测试仪的纳米模块对两个不同的柔性样品进行了压缩测试。测试是在非常低的载荷（1mm）下进行的。用纳米模块进行的纳米级压缩测试表明该模块有能力测试非常柔软和灵活的样品。本研究的额外测试可以通过Nanovea机械测试仪的多负载选项解决反复循环负载对弹簧状样品的弹性恢复方面的影响。</p>

<p>刹车片是复合材料，是一种由多种成分组成的材料，必须能够满足大量的安全要求。理想的刹车片具有高摩擦系数（COF），低磨损率，最小的噪音，并在不同的环境下保持可靠。为了确保刹车片的质量能够满足其要求，摩擦学测试可以用来确定关键规格。<br><br><br>刹车片的可靠性被放在非常重要的位置；乘客的安全永远不应该被忽视。因此，复制操作条件并确定可能的故障点是关键。<br>与纳诺维亚 <a href="https://nanovea.com/tribometers/">摩擦仪</a>，在销、球或平面与不断移动的反向材料之间施加恒定负载。两种材料之间的摩擦力通过刚性称重传感器收集，从而可以收集不同负载和速度下的材料特性，并在高温、腐蚀性或液体环境中进行测试。<br><br><br><br></p>
<p style="text-align: left; color: #1b96cf; font-size: 24px;">测量目标</p>
<p>在这项研究中，刹车片的摩擦系数是在从室温到700℃的持续升温环境下研究的。环境温度被就地提高，直到观察到刹车片的明显失效。一个热电偶被连接到针的背面，以测量滑动界面附近的温度。</p>

									<p>自2世纪发明以来，纸张在信息传播方面发挥了巨大作用[1]。纸张由交织在一起的纤维组成，这些纤维通常取自树木，经过干燥后成为薄片。作为信息存储的媒介，纸张使思想、艺术和历史得以远距离传播，并穿越时空。</p>
<p>如今，纸张普遍用于货币、书籍、盥洗用品、包装等。纸张通过不同的方式进行加工以获得与其应用相匹配的特性。例如，杂志上具有视觉吸引力的光面纸与粗糙的冷压水彩纸不同。纸张的生产方法会影响纸张的表面性能。这会影响墨水（或其他介质）如何沉淀在纸张上并出现在纸张上。为了检查不同的纸张工艺如何影响表面特性，Nanovea 通过使用我们的大面积扫描来检查各种类型纸张的粗糙度和纹理。 <a href="https://nanovea.com/profilometers/">3D 非接触式轮廓仪</a>.</p>

									聚碳酸酯镜片通常被用于许多光学应用中。它们的高抗冲击性、低重量和大批量生产的廉价成本使它们在各种应用中比传统玻璃更实用[1]。

其中一些应用需要安全（如安全眼镜）、复杂（如菲涅尔透镜）或耐用（如交通灯透镜）的标准，这些标准如果不使用塑料就很难满足。它能够廉价地满足许多要求，同时保持足够的光学质量，使塑料镜片在其领域中脱颖而出。聚碳酸酯镜片也有局限性。消费者最关心的问题是它们容易被刮伤。为了弥补这一点，可以进行额外的工艺来涂抹防刮伤涂层。

Nanovea通过利用我们的三种计量仪器来研究塑料镜片的一些重要特性。 <a href="https://nanovea.com/instruments/?p=profilometers">轮廓仪</a>, <a href="https://nanovea.com/instruments/?p=tribometers">摩擦仪</a>，以及 <a href="https://nanovea.com/instruments/?p=mechanicaltesters">机械测试仪</a>.
