Flexible and wearable sensing devices have broad application prospects in bio-monitoring such as pulse measurement,motion detection and voice recognition.In recent years,many significant improvements had been made to enhance the sensor’s performance including sensitivity,flexibility and repeatability.However,it is still extremely complicated and difficult to prepare a patted sensor directly on a flexible substrate.Herein,inspired by typography,a lowcost,environmentally friendly stamping method for the mass production of transparent conductive carbon nanotube (CNT) film is proposed.In this dry transfer strategy,a porous CNT block was used as both the seal and the ink;and Ecoflex film was served as an object substrate.Welldesigned CNT patts can be easily fabricated on the polymer substrate by engraving the target patt on the CNT seal before the stamping process.Moreover,the CNT film can be directly used to fabricate ultrathin (300 μm) strain sensor.This strain sensor possesses high sensitivity with a gauge factor (GF) up to 9960 at 85％ strain,high stretchability (＞ 200％) and repeatability (＞ 5000 cycles).It has been used to measure pulse signals and detect joint motion,suggesting promising application prospects in flexible and wearable electronic devices.
