The Best COVID-19-Fighting Technology at CES 2021

COVID-19 might have forced CES 2021 to become an all-digital affair, but it also inspired some of the most interesting—and perhaps useful—technologies at the show this year. 

From a temperature-taking doorbell, to UV-C lights intended to disinfect your smartphone and other items, to futuristic face masks with speakers and RGB lighting, COVID-19 technology has been a major trend at CES 2021.

Now, we can’t blame vendors for trying to cash in on the pandemic, but it remains to be seen whether any of these new technologies will prove useful at protecting the population and flattening the coronavirus curve. So while we hope that all of these innovations will be helpful, you should also continue to follow the CDC’s guidelines and recommendations to keep you and your loved ones protected.

LG’s COVID-19 Robot

LG's COVID-19 RobotCOVID-19-killing robot from LG. Meant for use in hotels, schools, offices, restaurants, and retail establishments, the robot can autonomously navigate a space and uses ultraviolet C (UV-C) light to disinfect “high-touch, high-traffic areas.” LG says it will be able to “move easily around tables, chairs, and other furniture, generally irradiating a room’s touchable surfaces in 15 to 30 minutes, disinfecting multiple areas on a single battery charge.” Motion detection sensors in the robot will help it avoid exposing any nearby humans to UV rays. The South Korean tech giant plans to launch the ‘bot in the US early this year.

The $119.99 accessory can also fast charge up to three devices simultaneously while disinfecting them. 


BioButtonsmartwatches and fitness trackers, including the Apple Watch Series 6 and Fitbit Sense, have useful COVID-19 features such as the ability to measure your Sp02 (blood oxygen saturation) level, but the BioButton is specifically designed to monitor your body for early signs of infection. The coin-sized device sticks to your skin and continuously measures your body temperature, respiration, and heart rate for 90 days. Based on your vital signs, it will tell you if you’re “cleared” or “not cleared” to leave for work or school each day.
