This ENGAGE proposal seeks funding for the feasibility study on the development of a smarter and more energy-efficient electromagnetic (EM) lock by incorporating low-cost sensing technologies. EM locks operate by electromagnetic forces and require continuous power consumption to remain locked. This research is motivated from the fact that there exist many applications where the door with an EM lock is rarely accessed in normal situation yet the EM lock has to remain locked all the time consuming unnecessary electric power. The main idea of this proposal is to investigate on the feasibility of monitoring the magnetic reluctance (or the magnetic resistance) through the existing electromagnet to detect initial and imminent attempt to open the door. If magnetic locks can be equipped with such a "self-sensing" capability, we can possibly run them with a very low effective holding force (i.e. drawing very little current) in most of time while no force is applied to open the door. This will bring significant energy saving since the full power can only be applied when an attempt is made to gain entry through the door. The technical objectives of the proposed research are 1) to investigate on the existing technologies of realtime monitoring of magnetic reluctance, and 2) to develop a reliable and cost-effective way to integrate such a sensing capability into the current EM locks.

该ENGAGE提案旨在通过整合低成本传感技术，为开发更智能，更节能的电磁（EM）锁的可行性研究寻求资金。EM锁通过电磁力操作，并且需要持续的功率消耗来保持锁定。这项研究的动机来自于这样的事实，即存在许多应用，其中具有EM锁的门在正常情况下很少被访问，而EM锁必须一直保持锁定，从而消耗不必要的电力。该提案的主要思想是研究通过现有电磁体监测磁阻（或磁阻）以检测开门的初始和即将发生的尝试的可行性。如果磁锁可以配备这样的“自感知”能力，我们可以在大部分时间内以非常低的有效保持力（即，汲取非常小的电流）运行它们，而不施加力来打开门。这将带来显著的节能，因为只有当试图通过门进入时才能施加全功率。拟议研究的技术目标是：1）调查现有的磁阻实时监测技术; 2）开发一种可靠且具有成本效益的方法，将这种传感能力集成到当前的电磁锁中。
