Measurement of a biomedical signal is representative method to detect whether drivers are drowsy. The biomedical signal fundamentally has oscillating properties, and that are obtained from high-sensitive pressure sensors. Here, we demonstrate a distinguished high-sensitive pressure sensor based on suspended 2D material. An acoustic signal is regarded as remote pressure signal in this work, and those are measured with real-time current variation. The optimized real-time signals are exhibited with a fast Fourier transform analysis and a noise cancellation method. We believe that our approach to the suspended 2D material-based pressure sensor paves the way for detecting biomedical signals well.
