    2013-4-23 · Structures were characterized by X-ray micro-CT (HMXST225; Nikon Metrology, Inc.). The nanowire piezoelectric response was calibrated under tensile strain , where the strain was calculated from the length change of the cylindrical hybrid structure. The bending strain field was determined using the calibrated nanowire strain sensors.

    1 天前 · The C-NGD sensor showed exceptional sensitivity and obvious curves of relative variations of electrical resistance. Similarly, the C-NGD sensor was attached on the human neck to real-time monitor the vibrations of swallowing (Fig. 6h). It can be seen that the electrical signal output was almost the same in each cycle of swallowing, indicating the superior stability and high sensitivity of the C-NGD sensor.

    Under a 10 s light spike, the EPSC rapidly increased to 5.3 nA and decay to 2.8 nA after 50 s. After 3000 s, the synaptic device still maintains an EPSC value of 1 nA (35% of the value within 50 s). The results suggest that our device exhibits stronger memory and can mimic long-term memory in the human brain.

    X-Ray power is proportional to the mA, so if all other parameters are similar, a 2 mA handheld generates an x-ray with about one quarter of the power of an 8 mA x-ray. When output power is lower, it is harder for the sensor or film to separate the signal from the noise, and this can result in lower image quality.
