"no complex/ moving parts or need for multiple antennas... auxetic metamaterials, withstand more than 10K compressions... frequency at which antenna is most efficient shifts due to its shape changes which can be captured for sensing, such as monitoring respiration as part of a wearable... also: tool lets users design/ produce metamaterial antennas for specific applications... biomedical wearables, curtains that adjust lighting, noise-cancelling toggling headphones, motion tracking, sensing for A/R, wireless communication"
