We systematically study the packaging effect on the performance of CMOS Thermoresistive Micro Calorimetric Flow (TMCF) sensors, including two types of sensor packaging designs: S-type and E-type. For S-type design, the experimental results indicate that not only the sensitivity of TMCF sensors was significantly changed by more than 30%, but also the flow range compared to the E-type design was dramatically...
The NTC thermistor nano-powders of Mn 1.05−y Co 1.95−x−z−w Ni x Mg y Al z Fe w O 4 were prepared by microemulsion method. Scanning electron microscope (SEM) image showed that the particles were well distributed. The mean particle-size was 72nm. The structure of the precursor was investigated with Fourier infrared...
Through analysis on the interaction and relationship between materials and airflow in the vertical pipe of an impeller blower, movement equations of materials flowing through the vertical pipe was established and the movement of materials was numerically simulated with the adoption of computer analysis software MATLAB. The reliability of the equations and numerical simulation was verified through...
Isotropically conductive adhesives (ICAs) have always been a hot spot in producing UHF RFID tag antennas with low cost for mass-production and low conductor loss.[1] As an interesting motif of flexible electronic component, they can also be integrated into sensors or as biocompatible electronic components in tissue engineering applications.[2] Considering the cost-effectiveness and the requirements...
We study the dynamic response characteristics of the piezoelectric ceramics (PZT) driver for many kinds of the irregular signals. The driver circuit can linearly amply many kinds of irregular signals with little distortion. When sinusoid signal is inputted, we measured the frequency response range of this circuit. When the frequency of the input sinusoid signal is in the range of 0-10 KHz, the distortion...
