  1. Pressure values presented in the paper are underestimated by a factor of 100

    In our published paper in Nanoscale Research Letters: Fernández et al. "Nanostructured giant magneto-impedance multilayers deposited onto flexible substrate for low pressure sensing" (Nanoscale Research Letters 2012 7:230 doi:10.1186/1556-276X-7-230), the pressure values are underestimated by a factor of 100, caused by an error in the conversion of pressure to SI units.

    The corrections should be applied to only specific points in the paper, and it doesn't affect the conclusions or the relevance of the research.

    -In the abstract:
    The sensitivity is 10 mOhm/Pa instead of 1 Ohm/Pa and the range of pressure is of 0 to 100Pa instead of 0 to 1 Pa .

    -In the experimental section:
    The maximum pressure value is 400 Pa instead of 4 Pa.

    -In the results an discussion section:
    The pressures of figure 4 are 0, 200 and 400 Pa respectively. And in Figure 5 must be applied a factor of 100 to the x axis.
    The comments about figure 5 from "10% of change between 0 and 1 Pa" to "10% of change between 0 and 100 Pa"

    -In the conclusion section:
    The average slope is 4 mOhm/Pa instead of 0.4 Ohm/Pa and the pressure sensitivity is of about 10 mOhm/ Pa between 0 an 100 Pa instead of about 1 Ohm/ Pa between 0 an 1 Pa.

    The authors would like to apologize for the inconveniences occasioned.
