SENSING SYSTEM AND SENSOR CHIP THEREOF

摘要

A sensing system includes a processing unit and sensor chip. The sensor chip includes a microelectrode array, a droplet space over the microelectrode array, and a plurality of control units coupled together in a daisy-chain configuration. Each of the control units is coupled to a respective one of the microelectrodes of the microelectrode array. The control units are controlled by the processing unit to drive movement of a droplet in the droplet space, and to inspect the droplet via the microelectrodes.

1. A sensing system comprising:
a processing unit configured to generate a data input signal, a clock signal, and a control input; and a sensor chip including: a microelectrode array including a plurality of microelectrodes spaced apart from each other; a cover disposed over said microelectrode array, disposed to receive a bias voltage signal, and formed with a droplet space for accommodating a droplet; and a plurality of control units, each of which includes a data input terminal and a data output terminal, is coupled to said processing unit for receiving the clock signal and the control input therefrom, and is coupled to a corresponding one of said microelectrodes for providing a microelectrode signal thereto, wherein said data input terminal of a first one of said control units receives the data input signal from said processing unit, and said data input terminal of each of other ones of said control units is coupled to said data output terminal of another one of said control units, such that said control units are coupled together in a daisy chain configuration.
