Correction to: Measuring Piezoelectric Output—Fact or Friction? (Advanced Materials, (2020), 32, 32, (2002979), 10.1002/adma.202002979)

Abstract

Adv. Mater. 2020, 32, 2002979 DOI: 10.2002/adma.202002979 The measured maximum voltage of approximately ±80 V that can be expected for an applied force of 10 N for a sample thickness of 100 µm, which is declared on page 6 in the published article, is hereby corrected: The corrected section of the text should read: “From Equations 1a–d, we can determine that for an applied force of 10 N (an approximate force of a controlled finger tap),[42] the maximum measured voltage that a sample would expect to have is approximately ±1 V for a 100 µm sample thickness (with a 4 cm2 area of compression, significantly higher than the area of a fingertip).” The context of this change is the discussion of erro..
