Abstract

The embodiments disclosed herein are directed to fabrication methods useful for creating MEMS via microcontact printing by using small organic molecule release layers. The disclose method enables transfer of a continuous metal film onto a discontinuous platform to form a variable capacitor array. The variable capacitor array can produce mechanical motion under the application of a voltage. The methods disclosed herein eliminate masking and other traditional MEMS fabrication methodology. The methods disclosed herein can be used to form a substantially transparent MEMS having a PDMS layer interposed between an electrode and a graphene diaphragm.
