About

Prakash Manandhar is a materials scientist whose pioneering work focuses on soft, stretchable electronics and ionic hydrogel sensors. His most significant contribution is the development of elastomeric ionic hydrogel sensors capable of measuring large mechanical strains—up to 25%—with exceptional linearity. By embedding dissolved salts within a flexible epoxy-amine polymer network, Manandhar created a homogeneous conductive gel that overcomes the polarization and hysteresis issues common in conventional ionic conductors. His 2012 paper on this topic, which has garnered 44 citations, demonstrates how AC sensing circuitry enables these hydrogels to function as reliable, drift-free strain gauges even in relatively dry conditions. This innovation bridges the gap between biological tissues and electronic devices, offering promising applications in soft robotics, wearable health monitors, and human-machine interfaces. Manandhar’s work is particularly noted for its elegant simplicity: using a single-phase material to achieve both elasticity and ionic conductivity without complex fabrication. His research continues to influence the design of next-generation flexible sensors that are durable, responsive, and biocompatible.
