    • A strain measurement device includes a strain gauge, a holding device, a transverse strain recorder, and a data processing device. The strain gauge includes at least one first and at least one second layers of carbon nanotube films, each layer of carbon nanotube films having a plurality of carbon nanotubes. The carbon nanotubes in at least one first layer of carbon nanotube film align along a first direction. The carbon nanotubes in at least one second layer of carbon nanotube film align along a second direction. The holding device is used to fasten a specimen and the strain gauge. The transverse strain recorder is used to record a transverse strain of the strain gauge. The data processing device is used to calculate an axial strain of the strain gauge.
    • 应变测量装置包括应变计,保持装置,横向应变记录器和数据处理装置。 应变计包括至少一个第一和至少一个第二层碳纳米管膜,每层碳纳米管膜具有多个碳纳米管。 碳纳米管膜的至少一个第一层中的碳纳米管沿第一方向排列。 碳纳米管薄膜的至少一个第二层中的碳纳米管沿第二方向排列。 保持装置用于固定样品和应变计。 横向应变记录仪用于记录应变仪的横向应变。 数据处理装置用于计算应变计的轴向应变。
