Inspired by the rolling mechanism of the proboscis of a butterfly, a rollable electronics which can be rolled and unrolled on demand is developed. The rollable platform provides sufficient force which grips onto the entire target surface without destroying the target. Micro bio-objects are gripped by using the rollable platform and their tiny motions are successfully detected with the sensor on the platform. Furthermore, detecting pulse wave signals of the swine is successfully conducted by rolling up the rollable system around the blood vessel of swine, which result proves the feasibility of rollable platform as a biomedical device.
