As the prototype sketch is nearing completion, we needed a little bit more information about the cardiac tissue properties. For the petri dish/arm complex, we wanted to utilize velco as a means of connecting the tissue to the device. The sketch could only be finalized once we were sure that the tissue could actually adhere to the velcro. Accordingly, we set up some test plates with various velcro apparatuses and grew tissue according to the pre-designed protocol.
