Methods and apparatus for sensing pressure are disclosed. With frequency domain power adaptation, the transmission power is allocated over the N\u2032 strongest subcarriers rather than over all possible N subcarriers, where the strongest subcarriers are understood to exhibit the highest channel gains. The nanostructures and the polymer host material form interfacial interactions that improve the useful life of the seal element by minimizing seal failures associated with explosive decompression, extrusion, spiral failure, abrasion, temperature degradation and the like.
