From: A biopotential optrode array: operation principles and simulations
Photo of a fabricated optrode sensor array prototype, with 13 × 18 vias with centre-centre spacing of 500 μm × 500 μm. The gold mirrors (ϕ = 250 μm) covering the liquid crystal side of the vias (ϕ = 60 μm) are visible through the glass substrate, and transparent ITO and liquid crystal layers. In practice, the device will be positioned such that the glass substrate will be at the bottom and vias facing upwards in contact with the biological sample (upside down relative to this view). The overall size of this prototype is 10 mm × 11.5 mm.
