Self-diagnostic approach for cell counting biosensor

Abstract

<span id="docs-internal-guid-66699b2e-7fff-5c7e-3931-5de920908f42"><span>In this research, a test monitoring strategy for an array of biosensors is proposed. The principle idea of this diagnostic technique is to measure and compare the impedance of each sensor in the array to achieve fully controlled online health monitoring technique at the system level. The work includes implementation of the diagnostic system, system architecture for analogue part, and SNR analysis. The technique has been applied on a cell coulter counting biochip where the design and fabrication of this sensing chip with electrodes make the coulter counter be an effective mean to count and analyses the cells in a blood sample. The experimental results show that the indication factor of the sensing electrodes has increased from 1 to 1.8 gradually depending on the fault level.</span></span>

Self-test and calibration methods for micro electro-mechanical systems

“…In contrast to IC trying out, MEMS trying out is on this manner greater exorbitant for the most part, talking to, in multiple cases, as much as 50% of the fetched of the realization product [9], [12]- [14]; integrated self-test (BIST) strategies can provide assist adjusted those cost-furnished publications of motion. All these are publicized to check over numerous areas of imperativeness and meddle [15]- [17]. Be that as it may, because of the prolonged complexity in comparison to ICs, BIST for MEMS as it have been risen in 1989 [18]- [22].…”
