This PFI: AIR Technology Translation project focuses on translating a motionless magnetic shape memory (MSM) micropump to fill the need for draining bodily fluids and delivering dosages with small, lightweight, and highly reliable micro fluidic pumps. The motionless MSM micropump is important because it enables dosage of micro fluids at higher precision and greater reliability which will advance research in many areas of biology, chemistry, and medicine. For instance the motionless MSM micropump will drain fluids from organs such as brain and lung continuously without or with minimally invasive surgery as opposed to removal of such fluids through repeated surgical interventions which is the current state of the art. The project will result in a scalable prototype of a motionless MSM micropump. This motionless MSM micropump has the following unique features: it is lightweight, actuated contact-free, and can transport a large range of volumes from picoliter to milliliter. These features provide advantages such as reliability, precision, versatility, contact-free actuation, low power consumption when compared to the leading competing peristaltic pumps and syringe pumps in this market space. This project addresses the following technology gaps as it translates from research discovery toward commercial application. The MSM pumping concept was demonstrated in 2012 at a pump actuated by a rotating permanent magnet. The micropump makes use of a magnetic shape memory alloy that shape-shifts in response to a dynamic magnetic field. Researchers will replace the rotating magnet with a set of electrical coils and a yoke turning the pump into a solid state device without moving parts. This will simplify the design, enable further miniaturization, and reduce weight. In addition, personnel involved in this project, including a post-doctoral engineering researcher and a MBA student, will receive experiences in innovation, product development and technology translation through combining a multifunctional, magneto-mechanical, smart material with electromagnetic field manipulation and through using a customer development process - namely the Lean Launchpad process - to build a sustainable business model around the motionless MSM micropump.The project engages the animal hospital WestVet to establish clinical needs for a micropump in context with bodily fluid drainage in this technology translation effort from research discovery toward commercial reality. The project also engages Idaho TechHelp to connect the researchers with manufacturers in Idaho and the region.

该PFI：空气技术翻译项目专注于翻译一种静止的磁性形状记忆(MSM)微泵，以满足排出体液和输送剂量的需要，该泵体积小、重量轻且高度可靠。静止的MSM微泵非常重要，因为它能够以更高的精度和更高的可靠性对微流体进行计量，这将促进生物、化学和医学等许多领域的研究。例如，静止的MSM微泵将在不需要或使用微创手术的情况下持续地从脑和肺等器官中排出液体，而不是通过重复的手术干预来清除这些液体，这是目前的技术状态。该项目将产生一个可伸缩的静止MSM微泵的原型。这种静止的MSM微型泵具有以下独特的特点：它重量轻，无接触驱动，可以传输从皮升到毫升的大范围体积。与市场上领先的蠕动泵和注射泵相比，这些特性提供了可靠性、精确度、通用性、非接触式驱动、低功耗等优势。该项目在从研究发现转化为商业应用的过程中解决了以下技术差距。MSM泵的概念于2012年在一个由旋转永磁体驱动的泵上进行了演示。微泵利用磁性形状记忆合金，其形状随着动态磁场的变化而改变。研究人员将用一组电子线圈和一个磁轭取代旋转的磁铁，将泵变成一个没有移动部件的固态设备。这将简化设计，实现进一步的小型化，并减轻重量。此外，参与该项目的人员，包括一名博士后工程研究员和一名MBA学生，将获得创新、产品开发和技术翻译方面的经验，通过将多功能、磁力机械、智能材料与电磁场操纵相结合，并通过使用客户开发过程-即精益Launchpad过程-来围绕静止的MSM微型泵建立可持续的商业模式。该项目与动物医院WestVet合作，在这项从研究发现到商业现实的技术转化工作中，建立对微型泵的临床需求。该项目还与爱达荷州TechHelp合作，将研究人员与爱达荷州和该地区的制造商联系起来。
