Imec and Holst Centre presented a 0.6V ECG readout chip in 40nm technology based on time-domain circuit techniques. The chip maintains consistent beat detection capabilities, even under movement (~40mVpp), paving the way to a low cost, low power multi-sensor Systems-on-Chip (SoCs) solution for wearable medical applications.   There is a clear need for emerging applications in personal healthcare to add more digital signal processing capabilities and memory storage within the system itself.
