Self-Powered All-in-One Wearable Bioelectronics Driven by Pneumatic Energy Buffering of Daily Footsteps. [PDF]
A pneumatic energy‐buffering strategy transforms transient and intermittent footsteps into quasi‐continuous electrical energy for a self‐powered wearable biosensing platform. The footwear‐integrated air‐pumping harvester, combined with the rationally designed power‐management system, powers a wearable ankle PPG device with reduced motion artifacts ...

Accurate Measurement Standard of AC RMS Voltage Using MEMS Electrothermal Devices [PDF]
Measurement standard for AC RMS voltage has been realized, by using thermal converters as AC-DC transfer standards in every country. AC-DC transfer standards provide a link for AC RMS voltage to DC voltage. Since thermal converters are physical artefacts,
