“Realistic 3D oblique cutaway illustration of a fully passive, wearable sweat-sensing patch. Show the patch at an angle with the layers peeled back. Include: Human skin surface at the bottom, with soft medical-grade adhesive layer and micro-holes for sweat collection. Transparent, soft microfluidic channels (PDMS or elastomer) directing sweat toward reservoirs, with visible passive valves (hydrophobic or swellable polymer) at channel junctions. 24 chrono-sequence reservoirs arranged radially, each larger shallow circular chamber (6–8 mm diameter, 0.5–1 mm deep) fed by multiple microchannels, showing sweat flowing in and color developing from a glucose colorimetric assay. 6–8 finger-actuated on-demand reservoirs around the patch periphery, each with a soft dome pump, single-channel feed, and visible colorimetric reaction. Shallow, wide reservoirs with reflective or white backing to amplify color contrast. Flexible substrate layer (PET or polyimide) supporting the channels and reservoirs. Sweat droplets visible in channels, filling reservoirs, clear color progression in chrono reservoirs. Clean scientific style, highly detailed, suitable for a PowerPoint slide, no text inside the image, realistic lighting, high clarity. Include a perspective that shows: Multi-channel feeding into larger colorimetric windows for chrono reservoirs Clear distinction between chrono and on-demand reservoirs All passive microfluidic features visible”
