摘要：
The invention relates to a minimally invasive instrument (1) comprising an enlargeable sensor head with a flat sensor element (7) that has resilient properties. In order to enable an improved minimally invasive instrument, the sensor element (7) comprises a film element (13) with a first layer (15) and with a second layer (17) distanced from the first layer (15) by means of spacers (19), wherein the sensor element (7) comprises, arranged between the layers (15, 17) of the film element (13), expansion-sensitive, polymer-based resistance elements (21) for picking up tactile stimuli.
