Aerosol spray lithography process. a–d Negative lithography. a Print the negative pattern of the contacts with standard toner (shown here in cyan), then spray on layer of aerosol conductor (shown here as metal ink). b Heat substrate at 65 °C to cure the conductive layer; increase the temperature to 155 °C and apply pressure onto aluminum foil and roll with cylinder. c Remove aluminum foil while on hotplate at 155 °C. d Reveal contact pattern on dielectric material. e–h Positive lithography. e Print positive of contacts with standard toner (shown here in cyan), then spray on layer of aerosol conductor (shown here as metal ink). f Heat substrate at 65 °C to cure conductive layer. g Soak in acetone to release off-contact areas. h Reveal contact pattern
