A differential resonant voltage sensor with frequency output was developed by bonding two quartz crystal double-ended tuning forks (DETFs) on both sides of a piezo bimorph. The applied voltage induced tensile and compression deformation in the upper and bottom layers of the piezo bimorph, which caused the resonant frequency of the dual DETFs to increase and decrease, respectively. In this case, the differential output of the resonance frequencies of the dual DETFs greatly reduced the effect of temperature drift. In addition, the input resistance of the piezo bimorph reached a few hundred GΩ, which caused almost no influence on the DC voltage under test. The fabricated device showed a linear characteristic over its measurement range of ±700 V with a sensitivity of 0.75 Hz/V, a resolution of 0.007% (0.1 V) and hysteresis of 0.76% of the full range. The quality factor of the DETFs was about 3661 (in air). This novel resonant voltage sensor with its extremely low power consumption is promising for measuring or monitoring DC voltage in various fields.

“…As such, there will be a need for the advanced management and effective use of these storage batteries and other energy resources. The measurement of power transfer is important not only for large-scale social infrastructures, but also for smart houses, and even when connecting electric vehicles to homes [1]. Safe and highly accurate measurement is needed that consumes only the smallest amount of stored power.…”

SUMMARY The Si resonator is applied for measuring the voltage in a highly isolated manner. The working principle is based on the resonant frequency shift caused by the electrical field from the electrode connected to the high‐voltage source (supposing the battery). Here, the resonator is electrically floated, and its potential is decided by the relative position against the electrodes which are connected to the high voltage and the driving voltage. The induced voltage on the resonator is analyzed against the driving frequency. The resonance is found by the paired peaks in the amplitude curve. The setup for the electrical measurement can make the sensor system compact. A new sensor design for avoiding the electrical field concentration realizes the measurement over 400 V without the breakdown. This will match with the high‐voltage dc power supply system.
