(abstract)

This paper presents a pioneering smart magnetic force sensor that combines a single-crystal diamond (SCD) MEMS resonator with a permanent magnetic particle through magnetic field gradient effect, enabling detection of ultraweak magnetic forces down to the femtonewton (fN) range. The sensor exhibits exceptional sensitivity of 7.15×103 ppm/(mT/mm) and low frequency fluctuation of 8.95×10-5 Hz, along with a rapid response time of 12.5 ms, making it suitable for high-precision measurements. Its design and functionality make it well-suited for diverse applications, from ultra-sensitive magnetic detection to innovative applications in miniaturized sensing systems.
