Description of Figures Figures comprising of photographs or images have not been included in this dataset. Figure 2: Development of the conductive ink with proper printability, high conductivity, and flexibility. a) Apparent viscosity as a function of shear rate for the inks with different PEO contents (wt%). b) Shear modulus as a function of shear stress for various inks. d) Plots of R /R t over time immediately after inks were printed with various solvent compositions (wt%) and the same Ag content in the dried ink (90 wt%). R t is the resistance of the ink dried in ambient environment for 30 min. e) Electrical conductivity of the dried inks as a function of silver flake content (n = 6). The solid line is a power law fit to the data using Equation 1 (R ‐square = 0.806). h) Yield stress of the inks as a function of Ag content (n = 4). i) Change of resistance of the ink filament with 90 wt% Ag as a function of bending radius (R ‐square = 0.977). Figure 3: Characterization of the wireless devices and the adaptive printing system c) The impedance responses and d) the inductances of coils with varying number of coil turns (n = 3). e) Impedance response of the printed inductive coil performing as a wireless moisture sensor when exposed to water vapor for different periods of time. f) Tracking error of the adaptive printing platform as a function of various moving speeds of the target surface (n = 2000), with a printer moving speed of 14 mm s−1 Figure 4: Demonstrations of adaptive 3D printing of functional electronic and biological materials c) Plot of the trajectory of the randomly moving hand and the adaptive toolpath of layer 1, both computed in real‐time by the visual tracking system. f) Impedance responses from the readout coil (inset) due to the change of moisture level of the surface of the human hand. Figure S2: Apparent viscosity as a function of shear rate for the inks with varying water content. All samples contained 12 wt% PEO in the solvent and 90 wt% Ag in the dried ink. Figure S4: Mechanical properties of the dried inks. b) Plots of stress-strain curves for the inks with different Ag contents. c) Young’s modulus as a function of Ag content(n= 4). d) Plots of stress-strain curves for the 90% Ag ink under cyclic tensile load. Figure S7: Design and characterization of the wireless power transmission system. b) The real part of impedances(n= 3), and c) Q factors of the printed inductive coils as functions of the numberof coil turns(n=3). Figure S8: Design and characterization of the wireless sensing system. d) The impedance responses from the readout coil when the wireless sensor was in the original state and in the recovered states after repeatedly going through the wetting and drying process(n= 4). The green shaded area shows the standard deviation of the recovery. Figure S10: Characterization of the adaptive printing system. b) An example of the speed profile of hand motion captured by the visual tracking system (mean: 2.4 mm/s; standard deviation: 1.1 mm/s; maximum: 7.8 mm/s). c) Tracking errors of the static and moving target surface under different moving speeds of the 3D printer(n= 2000).
