3D printed physical sensors. a,b) Schematic demonstration of material jetting (extrusion printing) in combination with reverse micelle to create patterned PSR.[11] The use of such a sensor to monitor deformation/strain on a human finger is shown in (b). Reproduced with permission.[11] Copyright 2014, Wiley-VCH. c) A multifunctional electronic skin (e-skin) with multimodal sensing capability that demonstrates miniaturization and elasticity enabled by 3D printing.[183] Inset shows e-skin attached on the hand. Reproduced with permission.[183] Copyright 2017, Wiley-VCH. d) Another example of 3D printed electronic skin comprising of highly stretchable and conformable conductive matrix network on polyimide substrate for multifunctional sensing (10 × 10 sensor array, scale bar: 5 mm).[184] e) Real-time sensing of temperature, pressure, and proximity by the sensor shown in (d).[184] f) A tactile sensor with the SEM showing the printed device (scale bar is 200 μm).[5a] Reproduced with permission.[5a] Copyright 2017, Wiley-VCH. g) A prosthetic hand that uses 3D printed pressure sensors for controlling the grip. Handling of a spherical object was used to demonstrate the pressure control.[185]
