Silicone with good thermal conductivity

I am looking for a material with the same properties of silicone (flexible, easy to manipulate, soft, etc.) but **without being a thermal isolate**.


I need this material to do the junction between a temperature sensor and the human skin (this is why I need it to be soft).


So far I've used the [ELASTOSIL® E43](https://www.wacker.com/cms/en/products/product/product.jsp?product=9037) but without good results.
