  • Publication number: 20220171000
    Abstract: A nanodevice provides for electric-field control of magnon-QSD interactions. The nanodevice includes a ferroelectric substrate, a ferromagnetic material disposed over the ferroelectric substrate, and a nanodiamond including an ensemble of nitrogen-vacancy (NV) spins, each NV magnetically interfacing with the ferromagnetic material. An electric field is measured by applying a voltage across the ferroelectric substrate and the ferromagnetic material, changing a magnon excitation spectrum of the ferromagnetic material with respect to an electron spin resonance frequency of the ensemble of NV spins, and measuring a relaxation rate of the ensemble of NV spins.

    Abstract: A single volume soft sensor capable of sensing real-time continuous contact and stretching. A low-cost and an easy method to fabricate such piezoresistive elastomer-based soft sensors for instant interactions is also provided. An electrical impedance tomography (EIT) technique is employed to estimate changes of resistance distribution on the sensor caused by fingertip contact. To compensate for the rebound elasticity of the elastomer and achieve real-time contact sensing, an adaptive baseline update for EIT is utilized. The baseline updates are triggered by fingertip contact and movement detections.
