Governments have underestimated the importance of technology governance in 5G development and will look to reassert control over key technologies. If future technologies are to be based on global standards, and not become geographically fragmented, the technology community need to urgently address this challenge.
The fifth generation of mobile phone technology — 5G — promises higher data rates and more reliable communication than previous generations, leading to a variety of novel applications. But to make this a reality, developments in a range of technologies will be required.
This Perspective provides a vision for sixth generation (6G) communications in which human-centric mobile communications are considered the most important application, and high security, secrecy and privacy are its key features.
A liquid metal printing technique can be used to create monolayer and bilayer indium tin oxide, with the bilayer samples offering a transparency above 99.3% and a sheet resistance as low as 5.4 kΩ □−1.
Pressure sensors with a sensitivity of ~103−107 kPa−1, as well as rapid response speeds, low power consumption and excellent stability, can be created by integrating a conductive microstructured air-gap gate with two-dimensional semiconductor transistors.
An analysis of skyrmion dynamics at different temperatures and electric drive currents is used to develop a complete description of the skyrmion Hall angle in ferromagnetic multilayers from the creep to the flow regime and illustrates that skyrmion trajectories can be engineered for device applications.
By using a scanning probe to control the polarization of ferroelectric polymers deposited on the surface of two-dimensional transition metal dichalcogenides, optoelectronic and unconventional memory devices can be created based on lateral p–n junctions.
An electron beam technique can be used to write high-resolution doping patterns in graphene and MoS2 van der Waals heterostructures, and could allow doped circuit designs to be created.
A conformable imager with a resolution of 508 pixels per inch, a speed of 41 frames per second and a total thickness of only 15 μm can be used to capture images of fingerprints and veins, and to map pulse waves.
Time-resolved measurements show that current-induced magnetization switching in ferrimagnetic devices is faster and more energy-efficient than in ferromagnet devices.
