  • Patent number: 11793439
    Abstract: Epidermal electronics are non-invasive and non-obstructive skin mounted sensors with mechanical properties matching human epidermis. Their manufacturing process includes photolithography and dry and wet etching within cleanroom facilities. The high cost of manpower, materials, photo masks, and facilities greatly hinders the commercialization potential of disposable epidermal electronics. In contrast, an embodiment of the invention includes a low cost, high throughput, bench top “cut-and-paste” method to complete the freeform manufacture of epidermal sensor system (ESS) in minutes. This versatile method works for many types of thin metal and polymeric sheets and is compatible with many tattoo adhesives or medical tapes. The resultant ESS is highly multimaterial and multifunctional and may measure ECG, EMG, skin temperature, skin hydration, as well as respiratory rate.

  • Publication number: 20200085336
    Abstract: A dual-mode epidermal sensor/electrode that, when worn on a human chest, is capable of synchronously/continuously monitoring electrical activity and mechano-acoustic activity of a cardiovascular system. The dual-mode epidermal sensor/electrode consists of a pair of stretchable electrocardiogram (ECG) electrodes made out of filamentary serpentine gold nano-membranes and a stretchable seismocardiogram (SCG) sensor comprising a filamentary serpentine PVDF. The dual-mode epidermal sensor/electrode is light, thin, flexible, and requires no operational power. The sensor can be laminated conformably and unobtrusively on a human chest to provide high fidelity ECG measurements and SCG measurements, and an estimated beat-to-beat blood pressure (BP). The dual-mode epidermal sensor is fabricated using a cost-effective, cut-and-paste method of construction.
