Abstract

We present a MEMS affinity glucose sensor that measures glucose concentrations via glucose-induced changes in the dielectric properties of a synthetic polymer. The sensor involves no mechanical moving parts for structural simplicity, and uses differential measurements for effective rejection of environmental interferences, thereby enabling accurate glucose detection. Our in-vitro and in-vivo experimental data demonstrate that this sensor can potentially be used for highly stable continuous glucose monitoring in diabetes care.
