Abstract: In this work, we used in situ acoustic emission (AE) sensors for online monitoring of part quality in a laser powder bed fusion (LPBF) additive manufacturing process. Currently, sensors such as thermo-optical imaging cameras ...

Abstract: This paper details the fabrication and testing of a combined temperature and expansion sensor to improve state of charge (SOC) and state of health (SOH) estimation for Li-ion batteries. These sensors enable the characterization ...
