Magnetoelectric (ME) sensors with a form factor of a few millimeters offer a comparatively low magnetic noise density of a few pT/Hz in a narrow frequency band near the first bending mode. While a high resonance frequency (kHz range) and limited bandwidth present a challenge to biomagnetic measurements. they can potentially be exploited in indirect sensing of non-magnetic quantities. ... https://macorners.shop/product-category/solar-light/
