Stretchable electronics, recently highlighted as novel devices, attempt the biomimicry of humans? stretchable skin while maintaining full functionality. The stretchability of electronic devices overcomes restrictions on applications for flexible electronics and provides even more options for applications since stretchability ensures that electronic devices are conformable to any curved surface and can even be wrapped around irregularly shaped objects and attached onto surfaces, stretching out and restoring back regularly or irregularly?

In the firs
t four decades of the semiconductor industry, the system performance was entirely dependent on transistor delay and power dissipation. With technology scaling, the transistor delay and power dissipation significantly reduced; however, a negative impact on the interconnect performance was realized. The reduction in the cross-sectional area of copper (Cu) interconnects resulted in higher resistivity under the effects of enhanced grain and surface scattering. Moreover, with smaller interconnect dimensions and higher operating frequency, the performance of Cu interconnects is gradually being limited by the electromigration effect, stability, operational bandwidth, and crosstalk. This trend is forcing researchers to find an alternative solution for high-speed very-large-scale integration (VLSI) interconnects.

Inorganic nanoparticles (NPs
) are small particles with diameters in the range of 1-100 nm. They have shown special and enhanced physical and chemical properties depending on the particle size. The four most common inorganic NPs are 1) noble metal, 2) magnetic, 3) fluorescence, and 4) ?multifunctional, e.g., luminescent magnetic. Table 1 shows the three major types of inorganic NPs and their special applications in medical devices.

Recent studie
s in the growing field of nanotechnology have been oriented toward the development of nanomechanical resonator systems. The ultrahigh frequency of nanoresonators facilitates a wide range of new applications such as ultrahigh-frequency-sensitive sensors, molecular transportation, high-frequency signal processing, biological imaging, quantum measurement, and radio-frequency communications. In this article, the applications of nanoresonators made of carbon nanotubes (CNTs) and graphene in sensors and molecular transportation are reviewed. Studies on the use of nanoresonators for the detection of atoms/molecules based on vibration and wave propagation analyses are outlined.
