To date, wearable health monitors for sensing electrical, photonic, and mechanical bio-signals have matured into viable commercial technologies; furthermore, the necessary technologies for realizing wearable electrochemical sensing are just beginning translation into demonstrable integrated systems. We have developed and tested integrated multimodal systems for the deployment of both electrochemical and photonic sensing on a wearable platform. As these systems mature, we have been able to evolve from non-invasive sweat sensing through to insertable sensor technologies. In this presentation, I will introduce the challenges associated with integrating biochemical sensors into insertables/implantables, and present the necessary design, fabrication, and performance changes necessary to realize such bioelectronic microsystems. Examples will include system optimization for metabolite sensing in sweat and sub-dermal oxygen sensing. Lastly, I will  most recently, I will conclude by presenting opportunities for future integration of both transdermal biofluid sample collection and transdermal sensing probes to evaluate the interstitial space to mine for critical measures of health and performance, including microsystems for transcutaneous measures of circulating hormones.
