To realise real-time, wearable personal health monitors, sensitive, low stiffness, inexpensive smart materials must be identified. Previously, room-temperature, low-viscosity nanocomposites based on graphene-doped Silly Putty (G-putty) were demonstrated. Displaying unprecedented electromechanical sensitivity and physical properties, G-putty is an ideal material to fill this niche. However, the relationship between processing conditions or indeed material properties and sensitivity is not known. Herein, we study the relationship between a number of processing parameters and the electromechanical properties of G-putty. We identify the processing conditions required to produce G-putty with gauge factors >100. In addition, we found a well-defined relationship between composite viscosity and sensitivity which shows maximised gauge factors for viscosities ~4 × 105 Pa · s. PAPER 2018
