Abstract
Soft, hydrated samples of biomaterials and live tissues are hard to characterize with standard equipment designed for engineering materials. To accommodate millimeter-scale samples with sub-kPa moduli, we designed a cantilever-based indentation system using piezoelectric actuators and capacitive sensors compatible with a variety of probe tips and sample holders. Embryonic mouse hearts, rat gastrointestinal tissues, human pancreas, and rat brain tissue have all been successfully characterized using this system.
