Rational designed microstructure pressure sensors with highly sensitive and wide detection range performance

Skin-Inspired Highly Sensitive Tactile Sensors with Ultrahigh Resolution over a Broad Sensing Range

“…The sensitivity and pressure detection range of our tactile sensor compared to those of previously reported tactile sensors are shown in Figure f. It should be noted that both the sensitivity and pressure sensing range in this work are better than most of the previously reported results. − These improved performances could be attributed to the unique construction of the tactile sensors. It is noted that the deformation of the composite films depends on the mechanical modulus of the composite.…”

Recent progress in flexible pressure sensors based on multiple microstructures: from design to application

“…In contrast, the spiny structure inside the porous interior has a high sensitivity over a broad pressure range due to its easy deformability. 151,152 For example, Li et al obtained PDMS/MWCNT films with internal porous and surface micropatterned structures by sacrificial template and microstructure processing methods (Fig. 5b 1 ).…”

“…Common sacrificial template methods include the ice template, emulsion template, chemical foaming, and the particle template method. 151,152 The frozen solvent in a mixture of polymers and nanofillers is used as a template, i.e. , the ice template method, which is a special sacrificial template method for the preparation of aerogels with highly porous structures.…”

BaTiO3/MXene/PVDF-TrFE composite films via an electrospinning method for flexible piezoelectric pressure sensors

“…In recent years, flexible pressure sensors have become a hot topic due to their advantages of flexibility, low cost, simple preparation, and high sensitivity, 1,2 and have been widely used in wearable electronics, 3–5 physiological signal detection, 6,7 environmental signal detection 8 and other fields. According to their sensing mechanisms, flexible pressure sensors can be mainly divided into piezoresistance, 9 capacitance, 10 piezoelectric, 11 and triboelectric sensors.…”
