Self-mixing interferometry is a well established interferometric measurement technique. In spite of the robustness and simplicity concept, interpreting self-mixing signal often complicated in practice, which detrimental to availability. Here we discuss use convolutional neural network reconstruct displacement target from semiconductor laser. The network, once trained on periodic patterns, can a...
This paper presents the first studies on robust closedloop deflection control of vanadium dioxide (VO2 )-based microactuators using self-sensing. The deflection output of the microactuator is estimated by VO2 resistance-based self-sensing through a high-order polynomial in order to eliminate the need for complicated external sensing mechanisms. An H∞ robust controller is designed and implemente...
Identifying episodes of significant stress is a challenging problem with implications for personal health and interface adaptation. We present the results of a study comparing multiple modalities of minimally intrusive stress sensing in real-world environments, collected from seven participants as they carried out their everyday activities over a ten-day period. We compare the data streams prod...
A self-contained fiber-optic immunosensor was developed to measure the 16,500-Da protein myoglobin. The sensing element was constructed by entrapment of Cascade Blue-labeled antibody within polyacrylamide gel at the distal face of an optical fiber 300 microns in core diameter. The polyacrylamide gel composition was optimized to allow diffusion of myoglobin but to exclude hemoglobin and higher-m...
