Material strategy for strain-invariant radio-frequency electronics
Abstract
Wearable and stretchable biointegrated electronics rely on integrated radio-frequency (RF) modules for control, power transfer, and communication, yet skin deformation disrupts resonance and degrades impedance matching and efficiency.The resonant frequency is determined by the effective electrical length and permittivity, but only the electrical length responds to tensile strain, leading to strain-sensitive behavior.A recent study reports a novel dielectric elastomer, termed a dielectro-elastic elastomer (DEE) with mechanically tunable permittivity for suppressing frequency shifts in RF electronics [1] .This tunable strategy enables strain-invariant RF performance and a skin-interfaced wireless health monitor with a stable 30 m operating range under 30% strain.
