Biosensor for monitoring an analyte content with a partial voltage generated therefrom
ActiveUS20050000806A1Reduce manufacturing costReduce power consumptionImmobilised enzymesBioreactor/fermenter combinationsElectrical resistance and conductanceAnalyte
A biosensor for monitoring an analyte content with a partial voltage generated therefrom is provided. The present biosensor includes a chip having a resistance Rs, a power source, and a microprocessor. The power source is used for supplying an applied voltage on the chip. The chip generates a time-dependent response current in response to a content of an analyte of a specimen applied thereon upon supplying the applied voltage on the chip. The microprocessor receives a time-dependent partial voltage caused from the chip due to the time-dependent response current, and determines the content of the analyte in accordance with the time-dependent partial voltage. The present biosensor is provided with fewer elements than a conventional one. A purpose of cost down is thus obtained.
