About
Sima Umrao is a leading researcher in the field of soft robotics and smart materials, with a primary focus on developing high-performance artificial muscles and tactile sensors. Her most significant contribution is the creation of MXene-based artificial muscles, where she demonstrated an ionically cross-linked Ti₃C₂Tₓ electrode that achieves ultrafast actuation responses within 1 second and an exceptionally large bending strain of 1.37% at ultra-low input voltages (0.1–1 V). This work, published in 2019 and cited 238 times, also showed remarkable long-term cyclic stability of 97% over 18,000 cycles, marking a major advance in kinetic soft robotics. In parallel, Umrao has pioneered hybrid electrode architectures for artificial touch, notably developing mutually exclusive p-type and n-type MoS₂/graphene electrodes for soft touch fingers. Her research addresses critical challenges in wearable robotics and smart mobile electronics, enabling rapid, low-voltage actuation with improved safety and energy efficiency. By combining two-dimensional materials with conducting polymers, Umrao has established new benchmarks for actuator performance, positioning her work at the forefront of next-generation haptic interfaces and biomimetic robotic systems.
