Q: Where are the most commercially interesting research areas in analog design?
A: There is a bunch. They include
antennae design (with spatial & directional differentation),
design & production of coordinated analog nervous stimulation events for each of the human senses using situated IoT emitters
low power IoT
consumer electrical grid, energy harvesting, geothermal, solar, storage…we propose upgrades to circuit panels that combine insulation from state terror signals with emergence of home battery backup/harvest storage & grid participation where relevant/feasible
sustaining & replenishing the power in hover drones
computing headsets for different motives: convenience, VR, spy privacy
sound & acoustical engineering with psychoacoustical goals
our meaning of smart/efficient buildings
