Electronic systems with physical properties matched to the human epidermis can be used in clinical monitoring. We report classes of electronic systems that achieve thicknesses, effective elastic moduli, bending stiffnesses, and areal mass densities matched to the epidermis. Unlike traditional wafer-based technologies, laminating such devices onto the skin leads to conformal contact and adequate adhesion based on van der Waals interactions alone, in a manner that is mechanically invisible to the… 
Mechanics of Epidermal Electronics
TLDR
The contact between EES and the skin is key to high-performance functioning of the above applications and is studied in this paper, which provides simple, analytical guidelines for design and optimization of EES with various possible functionalities.

Evaluating the Microwave Performance of Epidermal Electronics with Equivalent Transmission Line Modeling
TLDR
By demonstrating how the serpentine geometry and mechanics affect the power attenuation, electrical length, and impedance of microwave components, this work provides a crucial step forward in the development of hiah-nerformance wireless wearable electronics.
Lab-on-Skin: A Review of Flexible and Stretchable Electronics for Wearable Health Monitoring.
TLDR
The term "lab-on-skin" is introduced to describe a set of electronic devices that have physical properties, such as thickness, thermal mass, elastic modulus, and water-vapor permeability, which resemble those of the skin, which provide accurate, non-invasive, long-term, and continuous health monitoring.
Stable epidermal electronic device with strain isolation induced by in situ Joule heating
TLDR
A flexible surface electromyography (sEMG) sensor with outstanding stability and highly comfortable wearability is demonstrated, showing high accuracy for human hand gesture recognition, implying that the fabrication method proposed is a facile and reliable approach for the fabrication of epidermal electronics.
Epidermal electronics for seamless monitoring of biopotential signals
Medical deployment of electronics is often hampered by boxy and rigid packaging. Biological tissues are soft and curved, while electronic components are hard and angular. The mechanical mismatch can
A strain-absorbing design for tissue-machine interfaces using a tunable adhesive gel.
TLDR
Smart, stress-absorbing electronic devices that can adhere to wet and complex tissue surfaces and allow for reliable, long-term measurements of vital signals and arrays of highly sensitive, stretchable strain sensors using a similar design are demonstrated.
"Cut-and-paste" manufacture of multiparametric epidermal electronic systems
Epidermal electronics is a class of noninvasive and unobstructive skin-mounted, tattoo-like sensors and electronics capable of vital sign monitoring and establishing human-machine interface. The high
Epidermal radio frequency electronics for wireless power transfer
TLDR
This work introduces an epidermal, far-field radio frequency (RF) power harvester built using a modularized collection of ultrathin antennas, rectifiers and voltage doublers, and suggests robust capabilities for battery-free RF power, with relevance to many emergingEpidermal technologies.
