An international team of researchers developed a self-powered capsule that tests and disinfects water without batteries, filters, or chemicals. Three seconds of shaking generates enough electricity to measure water quality via Bluetooth, then floating motion powers disinfection — eliminating 99.9999% of microorganisms across 120+ cycles.

Kapsuli inayoelea husafisha maji ya kunywa kwa kutikisika tu — bila betri wala kemikali

DESIGNBOOM

Watafiti kutoka Chuo Kikuu cha Yonsei, Chuo Kikuu cha Bath, Chuo Kikuu cha Renmin cha China na KIST waliunda kapsuli inayojitegemea ambayo hupima na kuua vijidudu bila betri, vichujio, au kemikali. Kutikisika kwa sekunde tatu kunazalisha umeme wa kupima ubora wa maji kupitia Bluetooth; mwendo wa kuelea huanzisha usafi — 99.9999% ya vijidudu vinaangamizwa katika zaidi ya mizunguko 120.
