Our ability to trap, sort, and steer droplets on demand has revolutionized digital microfluidics and lab-on-a-chip devices, transforming fields such as diagnostics, chemical synthesis, and biological assays. Conventional platforms achieve such control by imposing electric, magnetic, or chemical gradients that create local surface‑tension differences to drive droplet motion. In this talk, I will present a fundamentally different strategy: using defect‑like surface features on soft, elastic substrates to program droplet transport. To this end, we leverage creases, which nucleate on elastic solids when compressed beyond a critical strain, as a rewritable motif to stop and steer droplets on demand. I will show that creases act as 'elastic brakes': they repel an approaching droplet through a far‑field elastocapillary interaction, halting it at a finite distance without ever pinning its contact line. Above a critical droplet size, however, the driving force overwhelms the elastic barrier and the droplet traverses the crease. By combining experiments and analytical modeling, we identify the key parameters that govern drop‑crease coupling and derive scaling laws for the repulsive force with distance. The resulting framework reveals how micro-morpholgy of creases modifies the droplet contact angles to alter its motion. I will conclude by showing how we harness this mechano‑adaptive interaction to achieve functionalities such as size and surface-tension-selective droplet sorting, programmable routing along reconfigurable paths, and droplet logic gates - all without external flows or electrical hardware.
