| abstract |
The invention relates to a load sensor comprising a polymer matrix and a piezo-ceramic material such as PZT, em¬ bedded in the polymer matrix, which together form a compos¬ ite, wherein the polymer matrix is a liquid crystalline resin, and wherein the piezo-ceramic material is a PZT powder forming 30-60% by volume of the composite, and wherein the PZT powder forms 40-50% by volume of the composite. |
