I am currently developing smart elastomers toward designing self-powered tactile and force sensors for soft robots. My research activities also involve the nanofabrication of rubber-based, micro-patterned, transfer-printed substrates for triboelectric and piezoelectric nanogenerators, energy storage, strain sensing, electromagnetic shielding etc.

Commercial rubber-based piezoresistive strain sensors for soft robotic actuators

widely used PDMS-based matrices offer certain shortcomings in terms of long-term operation and performance. On the other hand, commercially available rubbers offer multiple benefits. We exclusively employ commercial rubber-based conductors for the fabrication of ultrasensitive strain sensors for soft robotic components.

Robust, stretchable transfer-printed Triboelectric nanogenerators (TENG) using commercial rubbers for sustainable, affordable energy harvesting solutions

Crosslinked rubbers offer extreme robustness against friction and other mechanical deformations under a wide range of temperature, strain amplitude, and frequency. Moreover, a crosslinked rubber has very good abrasion resistance properties. For the TENG fabrication, rubbers could be the ultimate materials of choice for obvious reasons.

Design and fabrication of integrated hybrid piezoresistive-triboelectric sensors and arrays for E-skin developments

In contrast to unitary embedded sensor on soft robots, a sensor array can detect a large-scale dataset of tactile maps, which can be processed to identify various signals using convolutional neural networks. In addition, e-skin can cover larger surface of a soft robot and can record complex texture information by producing varied electrical voltage signal as a function of vibration, touch or force.
