Flow sensing experiments to demonstrate the enhanced sensitivity of the cupula-dressed sensors: (a) Naked hair cell sensor featuring a high-aspect ratio polymer pillar that interacts with the flow. (b) Hydrogel-dressed sensor showing the hydrogel cupula and the encapsulated nanofibrils. (c) Experimental results of air flow sensing conducted in wind tunnel (b) results of the water flow sensing experiments conducted in the water tunnel. The cupula encapsulated sensors showed an enhancement in sensitivity and resolution of flow sensing. (Image (a,b) were taken and edited by Ajay Giri Prakash Kottapalli).
