🔋 Ultrasound Tech Charges Implants Without Surgery
South Korean researchers have developed an ultrasound-based wireless charging system for medical implants like pacemakers — fully recharging in under 2 hours with no surgery required.
Using a new dual-layer piezoelectric module, the device captures nearly all ultrasonic energy, even what was previously lost. Tests showed a 140 mAh battery charged in 1h40min through 3 cm of water, and a 60 mAh battery in 1h20min through 30 mm of tissue.
