Recently, molecular or living cell-based thin materials with unique microstructure, properties, and functionality have been extensively studied for their uses in various applications. However, it is difficult to transport and manipulate thin materials with a thickness of around 0.001 mm safely without deforming or damaging them. To overcome this challenge, this talk will present an electrothermal manipulation bot. Our manipulator bot consists of a thermo-responsive hydrogel with aligned microchannels and a flexible electrical heating array that converts electricity to heat. The thermos-responsive hydrogel layer was fabricated to present microchannels, which can shrink and expand within 10 seconds in response to an electrothermal signal. The subsequent pressure change along the microchannels enables the manipulation bot to lift, hold, and deliver any thin cell sheets and electronic sensor arrays, like a cephalopods suction cup controlled by a bioelectric signal.
