An implantable actuation device that may be used with a glaucoma drainage device or attached to an ocular surface, a method of making an implantable actuation device, and a method of preventing cell adhesion resulting from a glaucoma treatment procedure. The implantable actuation device is made from a magnetoelastic material. Actuation of the magnetoelastic material may help control cellular adhesion that may develop and undesirably disrupt proper healing when recovering from invasive surgical treatments. The implantable actuation devices may have small form factors and customized geometries which include three-dimensional curvatures to help promote the actuation of liquid flow and facilitate the removal of unwanted cells.

Magnetoelastic implantable actuation device and method

A strain sensor having an active area that includes a magnetoelastic resonator and spring configured so that the spring undergoes a greater amount of strain than the resonator when the sensor is under load. The sensor is anchored at opposite ends of the active area to a substrate for which strain is to be measured. An interrogating coil is used for wireless sensor readout. A biasing magnet may be included to provide a desired sensor response for the particular application of the sensor. The strain sensor may be implemented as a differential strain sensor that includes a second, strain-independent reference resonator.
