Skin-mounted electrodes with nano spikes

Abstract

Epidermally mountable device includes terminus structures to enable positive connection with conductive tissue. The device includes nano spikes shaped to penetrate the epidermis of the skin to collect electrical biopotentials such as cardiac depolarization waveforms (ECGs) and various signals transmitted by implanted devices. Generally, the nano spikes are integrated on a substrate comprising, preferably, a flexible metalized conductive plate attachable to an adhesive backing. The device could be mounted on any external body of the patient to collect ECG, EEG or other signals. Further, the device is adaptable to include a programmable microprocessor, including memory and an antenna to store, receive and transmit data as needed. In one embodiment, in addition to collecting physiologic data through direct contact, the device may also be used as a smart patch to download, store and transfer data from implanted medical devices or other data sources using wireless data transmission medium.
