摘要: We present a 2nd-generation system for high-resolution structural-health monitoring of bridges and buildings. The combines large-area electronics (LAE) CMOS ICs via scalable interfaces based on inductive capacitive coupling. This enables architectures where the functional strengths both technologies can be leveraged to enable large-scale strain sensing cm resolution yet over sheets. consists three subsystems: (1) power-management subsystem, LAE is solar-power harvesting, power conversion regulation; (2) dense sensing, multi-sensor acquisition; (3) communication long-range interconnects, low-power transceivers. subsystem achieves 30% efficiency DC-AC inversion delivery IC 80.5% overall generating voltages DC-DC converters. has readout noise level 23 μStrainRMS (141 including sensor noise), at an energy/meas. 148 nJ 286 sensor-accessing control, respectively. energy/bit 14.6 pJ/4.3 pJ (Tx/Rx) distance 7.5 m data rate 2 Mb/s.
