Fingerprint‐Inspired Conducting Hierarchical Wrinkles for Energy‐Harvesting E‐Skin

Abstract: In the field of bionics, sophisticated and multifunctional electronic skins with a mechanosensing function that are inspired by nature are developed. Here, an energy-harvesting electronic skin (energy-E-skin), i.e., a pressure sensor with energy-harvesting functions is demonstrated, based on fingerprintinspired conducting hierarchical wrinkles. The conducting hierarchical wrinkles, fabricated via 2D stretching and subsequent Ar plasma treatment, are composed of polydimethylsiloxane (PDMS) wrinkles as the prima… Show more

“…The overwhelming majority of HMIs relies on tactile interactions ( Cao et al., 2018a ; Guo et al., 2020 ; Huang et al., 2020 ; Kang et al., 2019 ; Meng et al., 2018 ; Wu et al., 2018b , 2020 ; Xue et al., 2016 ; Yuan et al., 2017 ). From the traditional keyboards ( Ahmed et al., 2017 ; Chen et al., 2015 ; Jeon et al., 2018 ; Wang et al., 2018a ; Wu et al., 2018a ; Yang et al., 2013 ) and touch pads ( Chen et al., 2018 ; Dong et al., 2018 ; Shi et al., 2019a ) to the rising electronic skin ( Chang et al., 2020 ; Lai et al., 2016 , 2019 ; Wu et al., 2017 ), the tactile sensors are developed to be more flexible, sensitive, efficient, and multi-functional, even with human-like intelligence.…”

“…Extensive studies have been carried out on pressure sensor based on piezoresistive, [13,14] piezocapacitive, [15,16] piezoelectric, [17,18] and triboelectric [19,20] effects. For the temperature sensor, thermoresistive effect is widely employed; [21][22][23][24] while, sensors based on pyroelectric or thermoelectric effect are studied to less extent, which have advantages in selfpower capability.…”

“…The as-fabricated TENG could harvest energy from various types of irregular movements with the stretch ability from the TPU/Ag layer. The stretchable and tailorable TENG has been applied in both biomechanical monitoring and energy [98] Power source [84,87] Sensor [83,84,97,98] Polymer-semiconductor Power source [90,109] Sensor [88,91,103,109] 8 Research [101]. A flexible and modified PDMS film was applied as triboelectric layer, and the Au deposited on the backside of PDMS was selected as one electrode of TENG (Figure 4(e)).…”
