Correction: Efficient communication channel for smart contact lens with resonant magnetoquasistatic coupling

Equation 9 in the Section 2 Methodology and design, 2.1 Theoretical framework for resonant MQS coupling, “2.1.4 Choice of operating frequency and MQS validity”, Paragraph 1 was erroneously given as:

k R = 2 π R λ ≈ 0.08 ≪ 1

The correct equation is:

k R = 2 π R λ ≈ 0.04 ≪ 1

A correction has also been made in 3 Results, 3.7 Experimental validation, Paragraph 2. The following statement was incorrect: “(approximately −14dBm into 50 Ω)”. The correct text is: “A 200 mV_pp sinusoidal input is applied at the Tx, and the frequency is swept from 22 MHz to 30 MHz while the received spectrum is recorded at the Rx.”

The original article has been updated.
