Abstract
An correction is presented to correct Figure 5a in [Sensors, 2017, 17, 555].
The authors of [1] which to replace Figure 5a with the following:
Figure 5.
Strain sensitivity characteristics of proposed microbubble. (a) Wavelength shift of the interference fringe around 1555 nm as a function of tensile strain applied to the micro bubble; (b) Calculated sensitivity.
In this corrected figure, the data was fitted in exponential, but not linear function [1]. The authors regret this mistake. Thus, the fitted function can be depicted as Δλ = −11.39751 × exp(−δ/939.38195) + 11.54492. The corresponding sensitivity S could be calculated by differentiating the upper formula, which is S = 0.012133 × exp(−δ/939.38195), and the maximum strain sensitivity of the proposed microbubble is 12.133 pm/με.
The changes do not affect the scientific results. The manuscript will be updated and the original will remain online on the article webpage, with a reference to this Correction.
