Abstract
A sensing insert device (100) is disclosed for measuring a parameter of the muscular-skeletal system. The sensing insert device (100) can be temporary or permanent. Used intra-operatively, the sensing insert device (100) comprises an insert dock (202) and a sensing module (200). The sensing module (200) is a self-contained encapsulated measurement device having at least one contacting surface that couples to the muscular-skeletal system. The sensing module (200) comprises one or more sensors (303), electronic circuitry (307), a capacitor (1410), and communication circuitry (320). The capacitor (1410) powers the sensing module during a measurement process. An application specific integrated circuit (ASIC) increases power efficiency while reducing a form factor of the sensing module (200). The ASIC comprises power management circuitry (1412) and operational circuitry (1414). The power management circuitry (1412) couples a low-power energy source (1400) and operational circuitry (1414) to operate in one or more power conservation modes.
