Here, we report an intriguing type of sensing device composed of a Pt crack-based sensor in series with a polymer solar cell as a building block for energetically autonomous, wearable, and tactile sensor. This coplanar device enables human activity and physiological monitoring under indoor light illumination (2 mW/cm2) with acceptable and readible output signals. Additionally, the device can also function as a photodetector and a thermometer owing to the rapid response of the solar cell made from polymers. Consequently, the proposed device is multifuntional, mechanically robust, flexible, stretchable, and eco-friendly, which makes it suitable for long-term medical healthcare and wearable technology as well as environmental indication. Our designed green energy powered device therefore opens up a new route of developing renewable energy based portable and wearable systems. ? 2018 American Chemical Society.photodetector; self-powered electronics; strain sensor; stretchable optoelectronics; tactile sensor; temperature sensor[SDGs]SDG3[SDGs]SDG7Energy conservation; Energy policy; Environmental technology; Patient monitoring; Photodetectors; Photons; Polymer solar cells; Polymers; Renewable energy resources; Solar cells; Temperature sensors; Energy-saving devices; Mechanically robust; Multifunctional sensors; Physiological monitoring; Renewable energies; Self-powered; Strain sensors; Tactile sensors; Wearable sensors; platinum; activity tracker; devices; electronic device; equipment design; human; physiologic monitoring; procedures; renewable energy; solar energy; Equipment Design; Fitness Trackers; Humans; Monitoring, Physiologic; Platinum; Renewable Energy; Solar Energy; Wearable Electronic Devicesjournal article10.1021/acssensors.7b006902-s2.0-85041171454https://www.scopus.com/inward/record.uri?eid=2-s2.0-85041171454&doi=10.1021%2facssensors.7b00690&partnerID=40&md5=77ea260a3476abdb9481dbbee65e3dc6
