We have evaluated photoconductivities in diode connections using n-ch, p-ch, and pin-ch poly-Si TFTs for photosensor application. It is found that the photoconductivities increase as the illuminance increases for all the TFTs, but they do not change so much as the applied voltage changes. Moreover, the photoconductivities are: p-ch TFT < pin-ch TFT with the gate terminal to the p-type region <...
Artificial muscles employing soft actuators are recently promising for many applications, and ionic polymer-metal composites (IPMCs) are particularly remarkable. In this research, we have developed soft actuators using IPMCs driven with ionic liquid. It is expected that the bending ability continues for a long time regardless of the atmospheric humidity because of the non-volatileness.
We have developed maximum and minimum voltage sample and hold circuits employing operational amplifiers (OPAMPs) composed of polycrystalline silicon (poly-Si) thin-film transistors (TFTs). It was confirmed that the maximum and minimum voltages are successfully sampled and held. It was also confirmed that the restoring ratio has a peak near a certain value of the operation frequency. We would like...
We have developed a hybrid-type temperature sensor using thin-film transistors. First, we evaluate temperature dependences of transistor characteristics and find that the temperature dependence of the off-leakage current is much larger than that of the on current. Next, we combine a transistor, capacitor, and ring oscillator to develop the hybrid-type temperature sensor and detect the temperature...
Enhancement of subthreshold swing with increasing the channel layer thickness of bottom gate top contact type amorphous oxide TFT were evaluated by 2D device simulation with trap states induced in backchannel. The distance between the channel and the trap states induced in backchannel would be the main reason for the enhancement of the subthreshold swing. This effect is similar to one of the oxide...
