Special Report: Top Tech 2021

After months of blood, toil, tears, and sweat, we can all expect a much better year

Last January in this space we wrote that “technology doesn't really have bad years." But 2020 was like no other year in recent memory: Just about everything suffered, including technology. One shining exception was biotech, with the remarkably rapid development of vaccines capable of stemming the COVID-19 pandemic.

This year's roundup of anticipated tech advances includes an examination of the challenges in manufacturing these vaccines. And it describes how certain technologies used widely during the pandemic will likely have far-reaching effects on society, even after the threat subsides. You'll also find accounts of technical developments unrelated to the pandemic that the editors of IEEE Spectrum expect to generate news this year.

Making such predictions is, of course, risky. We trust, though, that whatever we may have missed won't possibly be as momentous as the earthshaker that we—indeed the whole world—didn't see coming 12 months ago.

The prototype patch in this research is shown in (a) on the left; on the right (b) is the kind of head rotation that can yield an electrical response from the patch.

Nelson Sepúlveda was sitting in the stands at Spartan Stadium, watching his hometown Michigan State players bash heads with their cross-state football rivals from the University of Michigan, when he had a scientific epiphany.

Perhaps the nanotechnologies he had been working on for years—paper-thin devices known as ferroelectret nanogenerators that convert mechanical energy into electrical energy—could help save these athletes from the ravages of traumatic brain injury.
