Three TRIZ-designed prototypes were tested and the average results across five measurement sets reportedly showed reductions of 100% (during a simulated WhatsApp conversation) and 90% (during a simulated standby mode with multiple radios on) in measured magnetic field compared with the phone without prototypes.",

  "summary": "This engineering study used TRIZ theory to design three prototypes intended to reduce magnetic fields generated by smartphones. Magnetic fields were measured under two simulated conditions (WhatsApp conversation and standby with multiple radios enabled) using a magnetic field tester. The authors report average reductions of 100% and 90% in measured magnetic field with the prototypes in the two conditions, and note that greater distance from the body corresponds to lower measured radiation.",
  "key_points": [
    "The study focuses on reducing a smartphone’s magnetic field using TRIZ-based prototype design.",
    "Two test scenarios were used: a simulated WhatsApp conversation and a standby mode with Wi-Fi, Bluetooth, data, GPS, and hotspot on.",
    "Magnetic fields were measured every 5 seconds for 3 minutes per set, with five sets averaged.",
    "The authors report that increased distance between phone and body is associated with lower measured radiation.",
    "Average results reportedly showed 100% reduction during the conversation condition with prototypes installed.",
    "Average results reportedly showed 90% reduction during the standby condition with prototypes installed.",
    "No direct human health outcomes are reported in the abstract; the outcome is reduction in measured magnetic field."
