Body heat-powered heart beat detection circuit

Technology Description The inventors have designed, implemented, and demonstrated an integrated circuit architecture for robust and automated detection of heartbeats from a two-electrode ECG signal. This uses sufficiently low power (~20μW) that it can be powered entirely by human body heat from a cm-scale TEG module at ~20mV, including wireless...

IC for Low Voltage and Self-Starting Thermoelectric Energy Harvesting

Technology Description Researchers at OSU have developed an integrated circuit that can cold start a DC-DC boost converter on a very small input voltage and combines a unique charge pump and very efficient DC-DC boost converter to maintain on-going operation at even lower input voltages. This IC is battery-free and can be made with conventional CMOS...

Wind turbine sensor array for monitoring avian and bat collisions v2.0

Technology Description An integrated multi-sensor detection package with event-based data collection has been developed using accelerometers, microphones, and a camera coupled with integrated signal processing. The sensors are installed directly on wind turbine blades and on-board processors wirelessly transmit data to the central controller and data...
