Flexible Tactile Actuator Arrays With Integrated Electroosmotic Pumps for Wearable Haptic Systems

Advanced Materials Technologies, EarlyView.
1 ×$\times$ 9 and 4 ×$\times$ 4 flexible tactile actuator arrays integrating electroosmotic pumps are developed to deliver pressure and vibration feedback on wearable platforms. Their thin, compliant structure conforms seamlessly to curved body surfaces, providing intimate contact and enhanced haptic sensations.

On the Aperture Efficiency of Intelligent Reflecting Surfaces [PDF]

IEEE Wireless Communications Letters, 2021
The concept of intelligent reflecting surfaces (IRS) has recently gained significant attention due to their ability to manipulate the impinging electromagnetic signals and offer anomalous reflections. In this letter, we derive and address the missing piece of prior works, namely the IRS aperture efficiency .

On the Optimal Number of Reflecting Elements for Reconfigurable Intelligent Surfaces [PDF]

IEEE Wireless Communications Letters, 2021
This work considers a point-to-point link where a reconfigurable intelligent surface assists the communication between transmitter and receiver. The system rate, energy efficiency, and their trade-off are optimized with respect to the number of individually tunable elements of the intelligent surface.
