摘要： The present invention relates to a hearing aid having feedback signal reduction function. A preferred embodiment of the hearing aid of the present invention having feedback signal reduction function comprises: a microphone; an A/D transformer transforming an external sound that is input through the microphone to a digital sound signal; a feedback signal detector detecting the feedback signal by testing a specific range of frequency from the digital sound signal; a feedback signal reducer, operated by the control of the feedback signal detector, renewing the coefficient of correlation of an adaptive filter, to which independent component analysis (ICA) is applied, and reducing the feedback signal; a frequency amplifier amplifying the digital sound signal by use of the compensation gain information per frequency to fit the pre-determined characteristics of hearing loss; a D/A transformer transforming the digital sound signal to an analog sound signal; and a receiver Accordingly, the present invention can reduce the feedback signal to deliver high-quality voice signals only.

摘要： Disclosed is a biosensor coated with an electroactive polymer layer demonstrating a bending behavior, more specifically a biosensor including an electroactive polymer layer coated on the surface of a bioreceptor and an electrode connected to the electroactive polymer layer. When an electrical stimulation is applied to the electrode, the electroactive polymer layer shows a bending behavior and thus the surface of the bioreceptor can be exposed to an analyte to allow a concentration analysis of the analyte. When used as an implantable biosensor, the disclosed biosensor may have a substantially increased life span since the bioreceptor can be selectively exposed to the analyte.

摘要： Disclosed is a biosensor to which an electroactive polymer layer is attached, more specifically, a biosensor including an electroactive polymer layer attached to the surface of a bioreceptor and electrodes connected to the electroactive polymer layer, which allows reversible deformation of the electroactive polymer layer when an electrical stimulation is applied to the electrode and can thereby analyze the concentration of an analyte when the surface of the bioreceptor is exposed to the analyte. When used as an implantable biosensor, the disclosed biosensor is advantageous in that the time period for which and the frequency with which the bioreceptor is exposed to the analyte can be adjusted, and thus the lifespan of the biosensor is considerably extended.
