Abstract
An aspect of this disclosure is an apparatus for transmitting power wirelessly. The apparatus comprises a detection circuit and a processor. The apparatus also includes a power amplifier driving an antenna circuit of flexible antenna(s) configured for wireless power transfer. The processor determines that at least one measured variable of the power amplifier falls outside of a corresponding threshold range, indicative of a deformation of a physical shape of one of the flexible antennas or indicative of misalignment of the flexible antennas from a power receiver. The processor further commands the power amplifier to transition to a first power mode from a second power mode based on the determination that at least one of the measured variables falls outside of the corresponding threshold range. The antenna circuit in the first power mode transmits power at a power level less than the power level in the second power mode.
