Extended Data Fig. 3: Assembly of sensor skins.
From: Resilient yet entirely degradable gelatin-based biogels for soft robots and electronics
Assembly process of the sensor skin consisting of degradable e-skin and reusable PCB. 1, Gels of different mechanical properties are joined by laser assisted rapid healing (LARH). 2–3, A zinc metal sheet is then applied to the gel and structured by a fiber laser. 4, After the structuring process the zinc residues are peeled off. 5, A flexible reusable PCB is mounted on the gel and soldered to the zinc foil of the e-skin. In the last fabrication step a temperature sensitive paste is placed on the gel to finalize the temperature sensor.
