Electromagnetic Interference Shielding Composites

Prof. Alexander Balandin, Dr. Fariborz Kargar and colleagues from the University of California, Riverside have developed novel composites with fillers comprised of graphene and/or quasi-1D van der Waals materials that provide efficient EMI shielding. These unique composites can block EM radiation and are also electrically insulating. These composites may be added to adhesives used in the packaging of electronic components so that the resulting electronic devices will have EMI shielding properties. This technology ensures that EMI shielding is achieved so that a variety of electronics operate reliably and without detrimental effects on human health.

Wearable electronics for health monitoring have gained increased interest after conformal tattoo-like electronic sensors were co-integrated on elastomeric sheets.  One of the design requirements in such wearable electronics was to carefully adjust the effective Young’s modulus and bending stiffness of the resulting layered electronics, and this has restrained the compact integration of the electronic components because the single transistor elements had dimensions that were in millimeter scale. The promise of tattoo-like epidermal electronics has inspired a significant research effort to optimize the mechanics of these structures.
