Professor Guo's research highlighted in the Journal of Polymer Science

Research of Ph.D. candidate Matthew Frenkel and Prof. Guo on "On-Chip Temperature Monitoring" was selected as the Cover Image in Journal of Polymer Science Part B: Polymer Physics, Vol. 54, Issue 12. In the associated article, Frenkel and Guo discussed the fabrication of a whispering gallery mode micro-sensor by utilizing polydimethylsiloxane (PDMS) micro-shells coated onto an electrical current-carrying wire. The sensor is capable of on-chip, dynamic, high-resolution temperature monitoring of an electrical wire and microelectronic chips/devices, and functions from room temperature to below 100 K. The use of PDMS allows for low-cost fabrication of sensors without risking thermal damage to the electronic component.
