High Detection Sensitivity

Gait is closely associated with many chronic diseases. With the development of the Internet of Health Things (IoHT), long-term gait monitoring and corresponding analysis can be performed remotely, reducing a patient’s time and traffic cost, while providing doctors more valuable gait information. The presented work provides a feasible means for real-time, long-term, and accurate gait monitoring in an IoHT scenario. Through the experimental results, the high detection sensitivity of 54 mN and responsivity of 163 mV/N are achieved, thereby satisfying the need for analyzing various diseases. Furthermore, 16 hours continuous working time indicates its successful utilization during long-term gait monitoring.

High Detection Sensitivity

We have engaged in researching and developing a large number of sensor devices using piezo-resistive cantilevers. The important technical features of our sensor devices lie in their very high detection sensitivity that has been achieved by the use of cantilevers of a very thin structure: as a typical example, force-detection sensitivity of about 10 pN has been achieved by using cantilevers of 300-nm thickness. This paper presents our developed sensor devices and applications and their respective features: more specifically, devices to directly measure object-contacting forces, devices embedded in an elastic body to measure its deformations, devices to measure air flows and vibrations, devices to measure differential air pressure, devices to measure differential pressure between cavities and external environment, and devices with cantilevers arranged on the liquid interface.

High Detection Sensitivity

Laser radar is a kind of active modern optical equipment, It’s the extension of traditional radio or microwave radar to optical frequency. Because the probe beam wavelength shortening and directional strengthen, so that the laser radar has very strong space, time resolution and high detection sensitivity and other advantages, Laser radar has been widely applied in the atmosphere, ocean, land and in other target detection. Optoelectronic isolator is usually used in electronic circuit device, but the ns order of magnitude of the high-speed triggering and synchronization is more difficult, while the synchronization of laser radar and laser communication is in the order of ns. In order to solve this problem, this paper presents a high speed optical trigger, which can realize the high speed synchronization of emission laser and receiving circuit in laser radar, and delay time is within 150ns, that can provide protection to obtain synchronous valid data.
