Dual Sensing Acousto-electric Sensor.

Simultaneous monitoring of multiple physiological parameters are highly desirable for disease diagnosis and management. However, simultaneous interrogations of parameters from miniaturized sensors can be difficult; to overcome this difficulties, we present the dual sensing acousto-electric sensor capable of simultaneously measuring pressure and pH. The dual sensing is achieved by two electrically decoupled LC tanks emitting RF signal at their respective resonant frequencies under ultrasonic excitation.

Light responsive plasmonic silicone elastomer/hydrogel soft actuator.

Soft robots offer unique advantages in their ability to interact with fragile organisms. Light responsive soft actuators are promising for the development of the untethered soft robots. However, this requires a mechanism for converting the externally applied light into mechanical actuation.
