Methods and systems for measuring one or more properties of a soft material employ air transmitted ultrasound that is reflected from the soft material to generate a mechanical wave in the soft material. A method of measuring one or more properties of a soft material includes transmitting ultrasound through air to an interface boundary between the soft material and air. Force is applied to the soft material by reflecting the ultrasound from the soft material. A mechanical wave is generated in the soft material as a result of the force applied to the soft material. Propagation of the mechanical wave in the soft material is measured with an imaging system. One or more properties of the soft material is determined based on the measured propagation of the mechanical wave in the soft material.

The present technology relates generally to intraocular pressure ('IOP') monitoring systems and associated devices and methods. In some embodiments, an intraocular pressure monitoring system configured in accordance with the technology comprises an implantable intraocular assembly and an external unit configured to transmit power to and receive data from the intraocular assembly. The intraocular assembly can include an IOP sensing device embedded within a flexible, expandable annular member. The IOP sensing device can include an antenna, a pressure sensor, and a microelectronic device encapsulated by an elastomer.

A light-emitting contact lens and a method and system for tracking a user's eye position using the light-emitting contact lens are disclosed. The eye position tracking can be used, for example, to allow the user to interact with a display device such that the position of the user's eye determines the image generated by the display device. Thus, as the user's eye moves, the image on the display device will be altered to represent the new position (e.g., viewing angle) of the user with regard to the display device.
