IMU Sensor to measure Tensile force

I am trying to measure the tensile force the mitral valve in the left heart exerts on the papillary muscle. I found a 3 axis water proof load cell that measure within the range of 0-10N, however it is outside my budget range. I am wondering is it possible to measure a tensile force with a IMU sensor, using the formula F=ma, with the accelerator of the IMU providing data on the acceleration.

Oh jes, rip open the chest, implant the IMU on the heart, glue things togather and read the acceleration. Rip it open again, tear out the haeart and measure the mass. Stitch togather again. Measure. Repat. Could be a bit difficult to find volunteers, but you never know.

I'll be using pig hearts for the experiment. Just wondering is it possible to measure a tensile force with an IMU sensor....(non sarcastic comments please)

Do not cross post.

Again: NO, you cannot measure forces using an accelerometer.
