Sensors
On-chip optical gas sensors have attracted a lot of attention in many fields such as the internet of things and point-of-care diagnosis due to their compactness and high scalability. However, the current laser-based on-chip absorption gas sensors have limited sensitivity caused by the optical thin property and strong interference fringe noise. Here, we report sensitive on-chip photothermal gas detection on an integrated lithium niobate photonic platform.

This dataset contains the extracted parameter data for the deep patellar tendon reflexes of four test subjects. Each subject was tapped with a reflex hammer with soft, medium, and hard taps three times. The dataset was collected by interpreting the spectrogram images from processed radar data and motion capture data.

To gather the dataset, we asked two participants to perform six basic knife activities. The layout of the system experiment is provided in Fig. 4. As it illustrates, we put the receiver on the right side and the ESP32 transceiver on the left side of the performing area. The performing area is a cutting board (30 x 46 cm) in this experiment. Each participant performs each activity five times in the performing area.

Human activity recognition (HAR) has attracted much attention. However, the existing HARs have shortcomings, such as few recognized activities, no identification, privacy leakage, and battery maintenance. Aiming at these shortcomings, this team has devised a body RFID skeleton that fully senses human activity and further proposes highly-accurate and fine-grained (total of 21 activities) HARs. The body RFID skeleton senses human activity by collecting tag response records of the skeleton node.

Solution processed all-inorganic lead halide perovskites are widely utilized to develop photodetectors (PDs) due to their excellent optoelectronic properties. The low-cost TiN electrode not only has better corrosion resistance than Ag electrode but also possesses good conductivity comparable to Au electrode, but the utilization of TiN electrode in perovskite PDs has been rarely reported.

The formation and changes of the pulse wave areaffected by the functional status of the heart, blood, and arterial vessels. The pulse signal covers pathological information in the cardiovascular system, and the doctor of traditional Chinese medicine (TCM) can diagnose diseases by feeling the pulse. The diagnosis of diseases through feeling the pulse of TCM primarily relies on the doctor’s feelings and subjective experience, and it lacks objectified data.
