# Froggit: Sensor and IoT innovations documented in 2026 **As of October 23, 2026, these six research demonstrations show concrete advances in battery-free sensing, wireless sensor networks, passive RFID, and sensing without electronic circuits. They are evidence of working prototypes—not, by themselves, evidence of broad commercial deployment.** 1. **Vibration-powered industrial sensing — WISE-Node.** Published August 21 in *Science Advances*, WISE-Node combines vibration energy harvesting with wireless sensing. The researchers report self-powered vibration sampling at **1,000 Hz**, **99.38%** accuracy identifying flange conditions, and tests on marine engines and generators.[^1] 2. **Self-calibrating, batter...
