Proxxi is a hardware and software company for industrial settings that has developed a wearable wrist-band to protect workers from electricity. Proxxi has repurposed their core product into a COVID-19 workplace distance and contact tracker wrist-band (entitled the Halo system or “Halo”). Halo vibrates to notify wearers that another band is within six feet (two meters), gently reminding workers of the need to maintain social distance.
