Shape memory alloy micro-actuators for medical applications
Most of the current ’applications’ of microelectromechanical systems can be found in the sensor field. The development of micro-actuators is severely hindered by the low power-to-volume ratio of most actuator technologies. Most of the presented micromotors also require reduction gearing and suffer from wear or fatigue problems. Shape Memory Alloy (SMA) actuators offer the advantage of extremely...
متن کاملMems Based Drug Delivery System Using Micropump
MEMS based Drug Delivery System (DDS) using an in-plane micropump enables us to make a compact, inexpensive system. This paper presents the new design of transdermal drug delivery system. A conceptual DDS design is proposed. This design consists of a unit which houses the micropump, electronic and power circuitry. This implantable unit is connected to a subcutaneous port via a silicone catheter...
متن کاملAn Electromagnetically-Actuated All-PDMS Valveless Micropump for Drug Delivery
This paper presents the fabrication process of a single-chamber planar valveless micropump driven by an external electromagnetic actuator. This micropump features a pair of micro diffuser and nozzle elements used to rectify the fluid flow, and an elastic magnetic membrane used to regulate the pressure in the enclosed fluid chamber. Polydimethylsiloxane (PDMS) is used as the main construction ma...
متن کاملComputational studies of shape memory alloy behavior in biomedical applications.
BACKGROUND Nowadays, shape memory alloys (SMAs) and in particular Ni-Ti alloys are commonly used in bioengineering applications as they join important qualities as resistance to corrosion, biocompatibility, fatigue resistance, MR compatibility, kink resistance with two unique thermo-mechanical behaviors: the shape memory effect and the pseudoelastic effect. They allow Ni-Ti devices to undergo l...
متن کاملClosed-loop On-demand Drug Delivery Micropump for Chronic Pain Management Applications
We present a low power (0.66-51.31mW) electrochemical micropump capable of accurate delivery of a diverse assortment of liquid drug formulations within a wide dynamic range of flow rates (0.33 141.9μL/min) suitable for chronic pain management applications. This system rapidly responds to changes in regimen (<1sec) for on-demand control and has an electrochemically based dose tracking system tha...
