Abstract

Bucky gel is a gelatinous mixture of carbon nanotubes and an ionic liquid. This mixture was employed in fabrication of a low-voltage, rapid, and dry electroactive bimorph actuator: Bucky Gel Actuator (BGA). Feasibility studies were carried out on BGA to evaluate its potential application as a new interface for flow regulation in microfluidics. Following the promising results, a flow regulator was designed and fabricated utilizing BGA as a microvalve. Flow rate measurements showed the capability of BGA microvalve in controlling the output flow rate in the range of 0.1-1 mL/min. BGA microvalve demonstrated great potential to be used for flow regulation in microfluidic devices for point-of-care devices and biomedical applications.

摘要

巴基凝胶是碳纳米管和离子液体的胶状混合物。这种混合物被用于制造一种低压、快速、干燥的电活性双折射执行器：巴基凝胶执行器（BGA）。对 BGA 进行了可行性研究，以评估其作为微流控中新型流量调节接口的潜在应用。在取得了有希望的结果后，设计并制造了一种利用 BGA 作为微阀的流量调节器。流量测量结果表明，BGA 微阀能够在 0.1-1 mL/min 的范围内控制输出流量。BGA 微阀在用于即时护理设备和生物医学应用的微流控设备中的流量调节方面具有很大的应用潜力。
