About

Ashok Chhetry is a leading researcher in the field of flexible and wearable electronics, with a primary focus on developing highly sensitive physical sensors for electronic skin (e-skin), soft robotics, and smart healthcare applications. His work centers on advanced material engineering, particularly the integration of novel nanomaterials like CaCu₃Ti₄O₁₂, MoS₂, and black phosphorus with laser-induced graphene and hybrid sponges to create next-generation pressure and strain sensors. Chhetry’s major contributions include pioneering strategies to dramatically enhance sensor sensitivity while achieving hysteresis-free and reliable performance—critical for real-world wearable devices. His highly cited 2020 paper on capacitive pressure sensors (225 citations) and his 2019 work on MoS₂-decorated graphene strain sensors (201 citations) have set benchmarks in the field. He also developed a groundbreaking black phosphorus-graphene heterostructure for temperature-strain hybridized sensing (194 citations), advancing multifunctional e-skin technology. More recently, his work on ultra-sensitive iontronic pressure sensors and cobalt nanoporous carbon-based strain sensors continues to push the boundaries of intuitive electronics and point-of-care diagnostics. With over 680 total citations from his top papers alone, Chhetry’s research is widely recognized for enabling reliable, cost-effective, and highly responsive wearable sensing platforms.
