低熔点金属基柔性三维生物医学微电极阵列采用相变法
Abstract(#br)In this study, we present a dimension-controllable 3D biomedical microelectrode based on low melting point metals (Bi/In/Sn/Zn alloy) applied using the phase transition method. We have established a process, in which the liquid metal is pumped through a syringe needle of the dispensing system to form a needle shape after cooling at room temperature. PDMS (polydimethylsiloxane) was chosen as the substrate of the electrode as it is amenable to micro-molding and has excellent flexibility.
