摘要： A miniature transducer for sensing muscle displacement substantially consists of a curved beam of high elastic compliance connected at its ends to two prongs. The prongs have sharpened tips which are insertable into the muscle under observation. A sensitive strain gauge is bonded to the beam preferably at the point of greatest curvature. The strain gauge output is directly related to changes in the beam curvature. As the muscle under observation expands the spacing between the prongs increases which decreases the beam curvature. On the other hand, when the muscle contracts the prongs' spacing decreases, thereby increasing the beam curvature.

摘要翻译： 用于感测肌肉位移的微型传感器基本上由其弹性柔顺的弯曲梁组成，其端部连接到两个尖头。 尖头具有尖锐的尖端，可以在观察下插入肌肉。 敏感的应变计优选地在最大曲率点处结合到梁上。 应变计输出与光束曲率的变化直接相关。 当观察到的肌肉扩大时，叉头之间的间距增加，这降低了束弯曲度。 另一方面，当肌肉收缩时，叉的间距减小，从而增加束弯曲度。
