Method of manufacturing strain gauge device, strain gauge device, and use of strain gauge device

摘要

A method for manufacturing a strain gauge device and a strain gauge device (20) are presented. The method comprises obtaining (11) a first substrate (21A), preferably a first formable substrate film (21A) for accommodating electronic components, printing (12) by a printed electronics method, such as by screen printing or inkjet printing, a strain gauge (22) on the first substrate (21A), and molding (14), preferably by utilizing injection molding, a molded material layer (23) embedding the strain gauge (22). The strain gauge device (20) may comprise two, preferably formable, substrate films between which the strain gauge (22) and the molded material layer (23) may be arranged.
