Scientists develop e-health patches to monitor pulse, blood pressure ANI | Updated: Apr 23, 2021 15:47 IST Tokyo [Japan], April 23 (ANI): Scientists at Osaka University, in cooperation with JOANNEUM RESEARCH (Weiz, Austria), introduced wireless health monitoring patches that use embedded piezoelectric nanogenerators to power themselves with harvested biomechanical energy. This work may lead to new autonomous health sensors as well as battery-less wearable electronic devices. The study was published in the journal Nature Communications. As wearable technology and smart sensors become increasingly popular, the problem of providing power to all of these devices become more relevant. While the energy requirements of each component may be modest, the need for wires or even batteries become burdensome and inconvenient. That is why new energy harvesting methods are needed. Also, the ability for integrated health monitors to use ambient motion to both powers and activate sensors will help accelerate their adoption in doctor's offices.
