Inspired by the rolling mechanism of the proboscis of a butterfly, rollable electronics that can be rolled and unrolled to a great extent on demand are developed. Generally, electronic devices that are attached to various surfaces to acquire biosignals require mechanical flexibility and sufficient adhesive force. The rollable platform provides sufficient force that grips onto the entire target surface without destroying the target organ. To prove the versatility of our device not only in gripping and detecting biosignals from micro objects but also in performing a variety of functions, thin-film electronics including a heater, strain sensor and temperature sensor are constructed on the rollable platform, and it is confirmed that all the electronics operate normally in the rolled and unrolled states without breakdown. Then, micro bio-objects are gripped by using the rollable platform, and their tiny motions are successfully detected with the sensor on the platform. Furthermore, the detection of the pulse wave signals of swine under diverse experimental conditions is successfully conducted by rolling up the rollable system around the blood vessel of the swine, the result of which proves the feasibility of a rollable platform as a biomedical device.

受到蝴蝶喙的滚动机制的启发，开发了可按需滚动和展开的可滚动电子产品。通常，附接到各种表面以获取生物信号的电子设备需要机械柔韧性和足够的粘附力。可滚动的平台提供足够的力，可以抓住整个目标表面，而不会破坏目标器官。为了证明我们的设备的多功能性，不仅可以抓握和检测来自微物体的生物信号，而且还可以执行多种功能，可滚动平台上构造了包括加热器，应变传感器和温度传感器在内的薄膜电子设备，这一点得到了证实。确保所有电子设备在展开和展开状态下均正常运行，而不会发生故障。然后，使用可滚动平台抓握微型生物对象，并使用平台上的传感器成功检测到它们的微小运动。此外，通过在猪的血管周围卷绕可滚动系统成功地进行了在各种实验条件下的猪的脉搏波信号的检测，其结果证明了可滚动平台作为生物医学装置的可行性。
