"recording brain activity/ stimulating neural tissues, they are flat, not conforming to neural structures' natural curves, require multiple fabrication steps... overcome developing μETF inspired plastic thermoforming 3D structures for neural electrodes... liquid crystal polymer substrate due to mechanical strength, biocompatibility, long-term stability... prototype reduced stimulation thresholds 1.7X, improved spatial resolution 2.2X... brain, spinal cord, cochlea, peripheral nerve neural interfaces, wearable electronics"
