In Kim et al.,Reference Kim, Torres, Islam, Islam, Chavez, Garcia Rosales, Wilburn, Stewart, Noveron, Tseng and Lin 1 a calculation error was made in the piezoelectric coefficient d 31 for 3D printed MWCNT/BT/PVDF nanocomposites. Output millivolts were used instead of volts in the equation to get the final d 31, so all values of d 31 should be divided by 1000 to get the correct values. A detailed list of corrections follows:
Abstract, line 5: the value 129 pC/N should be 0.13 pC/N. The sentence beginning “Measured d 31 of 3D printed…” should be deleted.
Page 5, right column, paragraph 2, line 7: the values 0.22 to 57.6 pC/N should be 0.002 to 0.058 pC/N.
Page 5, right column, paragraph 2, line 13: the values 21.8 (0 wt%-BT) to 129 pC/N (18 wt%-BT) should be 0.022 (0 wt%-BT) to 0.13 pC/N (18 wt%-BT).
Page 5, right column, paragraph 2, line 14: the sentence beginning “The measured d 31 of the nanocomposites is comparable…” should be deleted.
Page 7, left column, paragraph 1, line 6: the value of 129 pC/N should be 0.13 pC/N.
Figure 3 is corrected below.
