Details a new publication from Global Industry Analysts which says that the global market for EMI and RFI shielding materials and technologies is forecast to reach $9bn by 2024, driven by the rise in electromagnetic pollution caused by the explosive growth of mobile wireless communications and the resulting need to protect digital equipment from unwanted radio-frequency interference. Factors also driving growth in the market include: popularity of complex stacked chip package structures and multi-chip packages that increase sensitivity of next-generation electronic systems to EMI; growing demand for fail-proof and reliable electronics in the current digital era; cutting edge developments in shielding materials such as polymer matrix nanocomposites, carbon nanotubes, graphene and intrinsically conducting polymers; emerging new uses in electronic displays and photovoltaics in the form of EMI shielding conductive coatings; growing demand for next-generation integrated electronic circuits; increased burden of compliance with EMC regulations; and lower tolerance to equipment failures in the era of Internet of Things.
New polymer film that could make smartphones more bendable may one day be used to create tailor-made sensors that could non-invasively monitor biomedical metrics. The glass-like polymer being developed at Purdue University – made from long chains that contain radical groups – conducts electricity for transparent and flexible electronics. It is claimed that with the look and feel of glass, the polymer film can be inexpensively and sustainably produced on a large scale as it originates from earth-abundant materials. According to Purdue, its cost effectiveness also has advantages over polymers already used for electronics that rely on expensive chemistry and chemical doping to achieve high conductivity. The Purdue researchers are working to use this new polymer film to create tailor-made sensors that could non-invasively monitor glucose levels, heart rate or other biomedical metrics. The film could be modified, using specific molecules or ions, to target and selectively interact with various biological components inside the body. It could be worn as a nearly invisible patch on the skin.
