A spaser device comprises a graphene resonator and a carbon nanotube (CNT) gain element coupled via exciton-plasmon interaction. The graphene resonator may be a rectangular or square graphene nanoflake (GNF), and the CNT gain element may be characterised by chirality vector (n,m) selected such that the CNT has semiconducting properties. The CNT gain element may be illuminated using a light source having a photon energy corresponding with a first exciton energy (E.sub.22) of the CNT, whereby excitons having a second exciton energy (E.sub.11) less than the first exciton energy are generated in the CNT, and coupled to a surface plasmon (SP) mode of the graphene resonator. When the rate of generation of excitons having the second exciton energy exceeds a gain threshold, continuous spasing is established within the spaser device.

A system and method is provided for simulating a wellness promoting, DC variable electric field in an environment. A DC power source (DC input) and converter provide a DC output and generate an electric field in between positive and negative electrodes in an environment. An electric field detector measures and transmits information (data) about the strength of the actual electric field in the environment. A microprocessor receives the data and compares the information to the parameters of a wellness promoting electric field in order to direct the function of a pulse width modulator to modulate the DC output and thereby the DC variable electric field in real-time. The wellness of a subject in the environment of the DC variable electric field is enhanced by ensuring the positive electrode is proximal to a positive part of the subject and the negative electrode is proximal to a negative part of the subject.
